Once while eating dinner in Montreal, our friendly, intoxicated waitress plopped herself in my lap and proceeded to tell us about how obsessed she was with the CD that was playing - singing out the lyrics at an ungodly volume and flinging her arms about. Wow, I thought to myself, people who listen to Morcheeba sure seem to have a lot of fun, and promised to check them out.

Several CDs later, they are firmly one of my favorites. And their trip hop meditation, 2003’s Charango remains one of my most played CDs.

Morcheeba (Mor = more, Cheeba = pot) are brothers Ross and Paul Godfrey with singer Skye Edwards (who has since been replaced). Part trance, part ambience, Charango is full of smooth, snogworthy jams. And just as you surrender to its seductive groove, Slick Rick shows up with a rap called “Women Lose Weight”.

Lamenting his wife putting on weight after having kids and stalled by his mistress who wants a clean break before she shacks up with him, he decides the easiest way out of it all is to kill the spouse. Considering different ways to do the deed, he finally rams his car into her Chevy over a long lunch break one fine day. It is an unexpected, stunning, tongue-in-cheek social commentary that makes it a CD you won’t forget easily.

This is the 18th installment of The Rationalist, my column for the Times of India.

The man who gave us our national anthem, Rabindranath Tagore, once wrote that nationalism was “a great menace.” He went on to say, “It is the particular thing which for years has been at the bottom of India’s troubles.”

Not just India’s, but the world’s: In his book The Open Society and its Enemies, published in 1945 as Adolf Hitler was defeated, Karl Popper ripped into nationalism, with all its “appeals to our tribal instincts, to passion and to prejudice, and to our nostalgic desire to be relieved from the strain of individual responsibility which it attempts to replace by a collective or group responsibility.”

Nationalism is resurgent today, stomping across the globe hand-in-hand with populism. In India, too, it is tearing us apart. But must nationalism always be a bad thing? A provocative new book by the Israeli thinker Yael Tamir argues otherwise.

In her book Why Nationalism, Tamir makes the following arguments. One, nation-states are here to stay. Two, the state needs the nation to be viable. Three, people need nationalism for the sense of community and belonging it gives them. Four, therefore, we need to build a better nationalism, which brings people together instead of driving them apart.

The first point needs no elaboration. We are a globalised world, but we are also trapped by geography and circumstance. “Only 3.3 percent of the world’s population,” Tamir points out, “lives outside their country of birth.” Nutopia, the borderless state dreamed up by John Lennon and Yoko Ono, is not happening anytime soon.

If the only thing that citizens of a state have in common is geographical circumstance, it is not enough. If the state is a necessary construct, a nation is its necessary justification. “Political institutions crave to form long-term political bonding,” writes Tamir, “and for that matter they must create a community that is neither momentary nor meaningless.” Nationalism, she says, “endows the state with intimate feelings linking the past, the present, and the future.”

More pertinently, Tamir argues, people need nationalism. I am a humanist with a belief in individual rights, but Tamir says that this is not enough. “The term ‘human’ is a far too thin mode of delineation,” she writes. “Individuals need to rely on ‘thick identities’ to make their lives meaningful.” This involves a shared past, a common culture and distinctive values.

Tamir also points out that there is a “strong correlation between social class and political preferences.” The privileged elites can afford to be globalists, but those less well off are inevitably drawn to other narratives that enrich their lives. “Rather than seeing nationalism as the last refuge of the scoundrel,” writes Tamir, “we should start thinking of nationalism as the last hope of the needy.”

Tamir’s book bases its arguments on the West, but the argument holds in India as well. In a country with so much poverty, is it any wonder that nationalism is on the rise? The cosmopolitan, globe-trotting elites don’t have daily realities to escape, but how are those less fortunate to find meaning in their lives?

I have one question, though. Why is our nationalism so exclusionary when our nation is so inclusive?

In the nationalism that our ruling party promotes, there are some communities who belong here, and others who don’t. (And even among those who ‘belong’, they exploit divisions.) In their us-vs-them vision of the world, some religions are foreign, some values are foreign, even some culinary traditions are foreign – and therefore frowned upon. But the India I know and love is just the opposite of that.

We embrace influences from all over. Our language, our food, our clothes, our music, our cinema have absorbed so many diverse influences that to pretend they come from a single legit source is absurd. (Even the elegant churidar-kurtas our prime minister wears have an Islamic origin.) As an example, take the recent film Gully Boy: its style of music, the clothes its protagonists wear, even the attitudes in the film would have seemed alien to us a few decades ago. And yet, could there be a truer portrait of young India?

This inclusiveness, this joyous khichdi that we are, is what makes our nation a model for the rest of the world. No nation embraces all other nations as ours does. My India celebrates differences, and I do as well. I wear my kurta with jeans, I listen to ghazals, I eat dhansak and kababs, and I dream in the Indian language called English. This is my nationalism.

Those who try to divide us, therefore, are the true anti-nationals. We must reclaim nationalism from them.

This is the 20th installment of The Rationalist, my column for the Times of India.

Amit Shah’s induction into the union cabinet is such an interesting moment. Even partisans who oppose the BJP, as I do, would admit that Shah is a political genius. Under his leadership, the BJP has become an electoral behemoth in the most complicated political landscape in the world. The big question that now arises is this: can Shah do for India what he did for the BJP?

This raises a perplexing question: in the last five years, as the BJP has flourished, India has languished. And yet, the leadership of both the party and the nation are more or less the same. Then why hasn’t the ability to manage the party translated to governing the country?

I would argue that there are two reasons for this. One, the skills required in those two tasks are different. Two, so are the incentives in play.

Let’s look at the skills first. Managing a party like the BJP is, in some ways, like managing a large multinational company. Shah is a master at top-down planning and micro-management. How he went about winning the 2014 elections, described in detail in Prashant Jha’s book How the BJP Wins, should be a Harvard Business School case study. The book describes how he fixed the BJP’s ground game in Uttar Pradesh, picking teams for 147,000 booths in Uttar Pradesh, monitoring them, and keeping them accountable.

Shah looked at the market segmentation in UP, and hit upon his now famous “60% formula”. He realised he could not deliver the votes of Muslims, Yadavs and Jatavs, who were 40% of the population. So he focussed on wooing the other 60%, including non-Yadav OBCs and non-Jatav Dalits. He carried out versions of these caste reconfigurations across states, and according to Jha, covered “over 5 lakh kilometres” between 2014 and 2017, consolidating market share in every state in this country. He nurtured “a pool of a thousand new OBC and Dalit leaders”, going well beyond the posturing of other parties.

That so many Dalits and OBCs voted for the BJP in 2019 is astonishing. Shah went past Mandal politics, managing to subsume previously antagonistic castes and sub-castes into a broad Hindutva identity. And as the BJP increased its depth, it expanded its breadth as well. What it has done in West Bengal, wiping out the Left and weakening Mamata Banerjee, is jaw-dropping. With hindsight, it may one day seem inevitable, but only a madman could have conceived it, and only a genius could have executed it.

Good man to be Home Minister then, eh? Not quite. A country is not like a large company or even a political party. It is much too complex to be managed from the top down, and a control freak is bound to flounder. The approach needed is very different.

Some tasks of governance, it is true, are tailor-made for efficient managers. Building infrastructure, taking care of roads and power, building toilets (even without an underlying drainage system) and PR campaigns can all be executed by good managers. But the deeper tasks of making an economy flourish require a different approach. They need a light touch, not a heavy hand.

The 20th century is full of cautionary tales that show that economies cannot be centrally planned from the top down. Examples of that ‘fatal conceit’, to use my hero Friedrich Hayek’s term, include the Soviet Union, Mao’s China, and even the lady Modi most reminds me of, Indira Gandhi.

The task of the state, when it comes to the economy, is to administer a strong rule of law, and to make sure it is applied equally. No special favours to cronies or special interest groups. Just unleash the natural creativity of the people, and don’t try to micro-manage.

Sadly, the BJP’s impulse, like that of most governments of the past, is a statist one. India should have a small state that does a few things well. Instead, we have a large state that does many things badly, and acts as a parasite on its people.

As it happens, the few things that we should do well are all right up Shah’s managerial alley. For example, the rule of law is effectively absent in India today, especially for the poor. As Home Minister, Shah could fix this if he applied the same zeal to governing India as he did to growing the BJP. But will he?

And here we come to the question of incentives. What drives Amit Shah: maximising power, or serving the nation? What is good for the country will often coincide with what is good for the party – but not always. When they diverge, which path will Shah choose? So much rests on that.

Formal verification is a complex technology that has traditionally required experts or specialized teams who stood apart from the IC design and verification flow. Taking a different approach, a new release of the Cadence JasperGold formal verification platform (June 8, 2015) provides formal techniques that complement simulation, emulation, and debugging in the form of “Apps” or under-the-hood solutions that any design or verification engineer can use.

JasperGold was the initial (in fact only) product of Jasper Design Automation, acquired by Cadence in 2014. Jasper pioneered the formal Apps concept several years ago. While the company had previously sold JasperGold as a one-size-fits-all solution, Jasper began selling semi-automated JasperGold Apps that solved specific problems using formal analysis technology.

The new release is the next generation of JasperGold and will be available later this month. It includes three major improvements over previous Cadence and Jasper formal analysis offerings:

• A unified Cadence Incisive and JasperGold formal verification platform delivers up to 15X performance gain over previous solutions.
• JasperGold is integrated into the Cadence System Development Suite, where it provides formal-assisted simulation, emulation, and coverage. As a result, System Development Suite users can find bugs three months earlier than existing verification methods.
• JasperGold’s formal analysis engines are integrated with the recently announced Indago debug platform, automating root cause analysis and on-the-fly, what-if exploration.

Best of Both Formal Verification Worlds

Taking advantage of technologies from both Cadence and Jasper, the new JasperGold represents a “best of both worlds” solution, according to Pete Hardee, product management director at Cadence. This solution combines technologies from the Cadence Incisive Enterprise Verifier and Incisive Formal Verifier with JasperGold formal analysis engines.

For example, to ease migration from Incisive formal tools, Cadence has integrated an Incisive common front end into the JasperGold apps platform. Jasper formal engines can run within the Incisive run-time environment. Cadence has also brought some selected Incisive formal engines into JasperGold.

As shown to the right, the JasperGold platform supports both the existing JasperGold front-end parser and the Incisive front-end parser. Hardee observed that this dual parser arrangement simplifies migration from Incisive formal tools to JasperGold, and provides a common compilation environment for people who want to use JasperGold with Incisive simulation. Further, the common run-time environment enables formal-assisted simulation.

The combination of JasperGold engines and Incisive engines supports two use models for formal analysis: formal proofs and bug hunting. In the first case, formal engines try all combinations of inputs without a testbench. The test is driven by formal properties written in languages such as SVA (SystemVerilog assertions) or PSL (Property Specification Language). Completion of a property is exhaustive proof that something can or cannot happen. This provides a “much stronger result” than simulation, Hardee said.

He also noted that formal analysis doesn’t necessarily require that all properties are completed. “You can get a lot of value even if proofs don’t complete,” he said. “Proofs that run deep enough to find bugs are just fine.”

Bug hunting involves random searches, and JasperGold bug hunting engines are very fast. However, these engines don’t necessarily use the most optimal path to get to a bug. So, Cadence engineers brought a constraint solver from Incisive and integrated it into JasperGold. “It looks at the constraints in the environment and gives you a better starting point,” Hardee said. “It takes more up-front time, but once you’ve done that the bug hunting engines can actually take a shorter path and find a bug a lot quicker.”

Another new JasperGold capability from the Incisive Formal Verifier is called “search pointing.” This uses simulation to penetrate deeply into the state space, and then kicks off a random formal search from a given point that you’ve reached in simulation. This technique makes it possible to find bugs that are very deep in the design.

It is probably clear by now that a number of different formal “engines” may be required to solve a given verification problem. Traditionally, a formal tool (or user) will farm a problem out to many engines and see which one works best. To put more intelligence into that process, Cadence launched the Trident “multi-cooperating engine” a couple of years ago. That has now been brought into JasperGold, where it helps “orchestrate” the engines according to what will work best for the design. This is a big part of the reason for the 15X speedup noted earlier in this post.

Integration with System Development Suite

The Cadence System Development Suite is an integrated set of hardware/software development and verification engines, including virtual prototyping, Incisive simulation, emulation, and FPGA-based prototyping. As shown below, JasperGold technology is integrated into the System Development Suite in several places, including formal-assisted debug, formal-assisted verification closure, formal-assisted simulation, formal-assisted emulation, and the Incisive vManager verification planning tool.

Formal-assisted emulation sounds like it should be easy, especially since Cadence has both accelerated verification IP (VIP) and assertion-based VIP. However, there’s a complication. Accelerated VIP represents less verification content than simulation VIP, because you have to remove many checkers to get VIP to compile on a Palladium emulator. That’s because the Palladium requires synthesizable code.

What you can do, however, is use assertion-based VIP in “snoop mode” as shown below. Assertion-based VIP coded in synthesizable SystemVerilog can replace the missing checkers in accelerated VIP. In this diagram, everything in the green box is running in the emulator and is thus completely accelerated.

Another example of formal-assisted emulation has to do with deep traces. As Hardee noted, emulation will produce very long traces, and it can be very difficult to find a point of interest in the trace and determine what caused an error. With formal-assisted emulation, users can find interesting events within the traces and create properties that mark them, so a debugger can find these events and trace back to the root cause.

Formal-assisted verification closure is available with the new JasperGold release. This is possible because you can use the vManager product to determine which tasks were completed by formal engines. It’s important information for verification managers who are not used to formal tools, Hardee noted.

Another aspect of formal-assisted verification closure is the JasperGold Unreachability Analysis (UNR) App, which can save simulation users weeks of time and effort. This App takes in the simulation coverage database and RTL, and automatically generates properties to explore coverage holes and determine if holes are reachable or unreachable. The App then generates an unreachable coverage point database. If the unreachable code does something useful, there’s a bug in the design or the testbench; if not, you don’t have to worry about it. The diagram below shows how it works.

Formal-Assisted Debugging

The third major component of the JasperGold announcement is the integration of formal analysis into the Indago debugging platform. As shown below, this platform has several apps, including the Indago Debug Analyzer. Two formal debug capabilities from the Jasper Visualize environment have been added to the the Indago Debug Analyzer:

• Highlight Relevant Logic: This highlights the “cone of influence,” or the logic that is involved in reaching a given point
• Why: This button highlights the immediate causes for a given event, and allows users to trace backwards in time

More formal capabilities will come with the Indago Advanced Debug Analyzer app, scheduled for release towards the end of 2015. This includes Quiet Trace, a Jasper capability that reduces trace activity to transactions relevant to an event. Also, a what-if analysis allows on-the-fly trace editing and recalculation to explore effects and sensitivities, without having to re-compile and re-execute the simulation.

Finally, Cadence has a Superlint flow that is now fully integrated with the JasperGold Visualize debugger. This two-tiered flow includes a basic lint capability as well as automated formal analysis based on the JasperGold Structural Property Synthesis app. “This could be a very good entry point for designers to start using formal,” Hardee said.

“Formal is taking off,” Hardee concluded. “People are no longer talking about return on investment for formal—they have established that. Now they’re supporting a proliferation of formal in their companies such that a wider set of people experience the benefit from that proven return on investment.”

There has been so much hype about the “Internet of Things” (IoT) that it is refreshing to hear about a cutting-edge development project that can bring concrete benefits to millions of people. That project is the ongoing development of the Google Smart Contact Lens, and it was detailed in a keynote speech June 8 at the Design Automation Conference (DAC 2015).

The keynote speech was given by Brian Otis (right), a director at Google and a research associate professor at the University of Washington. The “smart lens” that the project envisions is essentially a disposable contact lens that fits on an eye and continuously monitors blood glucose levels. This is valuable information for anyone who has, or may someday have, diabetes.

Since he was speaking to an engineering audience, Otis focused on the challenges behind building such a device, and described some of the strategies taken by Google and its partner, Novartis. The project required new approaches to miniaturization, low-power design, and connectivity, as well as a comfortable and reliable silicon-to-human interface. Otis discussed the “why” as well and showed how the device could potentially save or improve millions of lives.

Millions of Users

First, a bit of background. Google announced the smart lens project in a blog post in January 2014. Since then it has been featured in news outlets including Forbes, Time, and the Wall Street Journal. In March 2015, Time reported that Google has been granted a patent for a smart contact lens.

The smart lens monitors the level of blood glucose by looking at its concentration in tears. The lens includes a wireless system on chip (SoC) and a miniaturized glucose sensor. A tiny pinhole in the lens allows tear fluid to seep into the sensor, and a wireless antenna handles communications to the wireless devices.

“We figure that if we can solve a huge problem, it is probably worth doing,” Otis said. “Diabetes is one example.” He noted 382 million people worldwide have diabetes today, and that 35% of the U.S. population may be pre-diabetic. Today, diabetics must *** their fingers to test blood glucose levels, a procedure that is invasive, painful, and subject to infrequent monitoring.

According to Otis, the smart contact lens represents a “new category of wearable devices that are comfortable, inexpensive, and empowering.” The lens does sensor data logging and uses a portable instrument to measure glucose levels. It is thin, cheap, and disposable, he said.

Moreover, the lens is not just for people already diagnosed with diabetes—it’s for anyone who is pre-diabetic, or may be at risk due to genetic predisposition. “If we are pro-active rather than re-active,” Otis said, “Instead of waiting until a person has full-fledged diabetes, we could make a huge difference in peoples’ lives and lower the costs of treating them.”

Technical Challenges

No one has built anything quite like the smart lens, so researchers at Google and Novartis are treading new ground. Otis identified three key challenges:

• Miniaturization: Everything must be really small—the SoC, the passive components, the power supply. Components must be flexible and cheap, and support thin-film integration.
• Platform: Google has developed a reusable platform that includes tiny, always-on wireless sensors, ultra low-power components, and standards-based interfaces.
• Data: Researchers are looking for the best ways to get the resulting data into a mobile device and onto the cloud.

Comfort is another concern. “This is not intended to be for the most severe cases,” Otis said. “This is intended to be for all of us as a pro-active way of improving our lifestyles.”

The platform provides a bidirectional encrypted wireless link, integrated power management, on-chip memory, standards-based RFID link, flexible sensor interface, high-resolution potentiostat sensor, and decoupling capacitors. Most of these capabilities are provided by the standard CMOS SoC, which is a couple hundred microns on a side and only “tens of microns” thick.

Otis noted that unpackaged ICs are typically 250 microns thick when they come back from the foundry. Thus, post-processing is needed so the IC will fit into a contact lens.

Furthermore, the design requires precision analog circuitry and additional environmental sensors. “Some of this stuff sounds mundane but it is really hard, especially when you find out you can’t throw large decoupling capacitors and bypass capacitors onto a board, and all that has to be re-integrated into the chip,” Otis said.

Sensor Challenges

Getting information from the human body is challenging. The smart lens sensor does a direct chemical measurement on the surface of the eye. The sensor is designed to work with very low glucose concentrations. This is because the concentration of glucose in tears is an order of magnitude lower than it is in blood.

In brief, the sensor has two parallel plates that are coated with an enzyme that converts glucose into hydrogen peroxide, which flows around the electrodes of the sensor. This is actually a fairly standard way of doing glucose monitoring. However, the smart lens sensor has two electrodes compared to the typical three.

In manufacturing, it is essential to keep costs low. Otis outlined a three-step manufacturing process:

• Start with the bottom layer, and mold a contact lens in the way you typically would.
• Add the electronics package on top of that layer.
• Build a second layer that encapsulates the electronics and provides the curvature needed for comfort and vision correction.

Beyond the technical challenges are the “clinical” challenges of working with human beings. The human body “is messy and very variable,” Otis said. This variability affects sensor performance and calibration, RF/electro-magnetic performance, system reliability, and comfort.

The final step is making use of the data. “We need to get the data from the device into a phone, and then display it so users can visualize the data,” Otis said. This provides “actionable feedback” to the person who needs it. Eventually, the data will need to be stored in the cloud.

As he concluded his talk, Otis noted that the platform his group developed may have many applications beyond glucose monitoring. “There is a lot you can do with a bunch of logic and sensing capability,” he said, “and there are hundreds of biomarkers beyond glucose.” Clearly this will be an interesting technology to watch.

- Gary Smith at DAC 2015: How EDA Can Expand Into New Directions

EDA investor and former executive Jim Hogan is optimistic about automotive electronics, but he has some concerns as well. At the recent Design Automation Conference (DAC 2015), he delivered a speech titled “The Looming Quality, Reliability, and Safety Crisis in Automotive Electronics...Why is it and what can we do to avoid it?"

Hogan gave the keynote speech for IP Talks!, a series of over 30 half-hour presentations located at the ChipEstimate.com booth. Presenters included ARM, Cadence, eSilicon, Kilopass, Sidense, SilabTech, Sonics, Synopsys, True Circuits, and TSMC. Held in an informal setting, the talks addressed the challenges faced by SoC design teams and showed how the latest developments in semiconductor IP can contribute to design success.

Jim Hogan delivers keynote speech at DAC 2015 IP Talks!

Hogan talked about several phases of automotive electronics. These include assisted driving to avoid collisions, controlled automation of isolated tasks such as parallel parking, and, finally, fully autonomous vehicles, which Hogan expects to see in 15 to 20 years. The top immediate priorities for automotive electronics designers, he said, will be government regulation, fuel economy, advanced safety, and infotainment.

More Code than a Boeing 777

According to Hogan, today’s automobiles use 50-100 microcontrollers per car, resulting in a worldwide automotive semiconductor market of around $40 billion. The global market for advanced automotive electronics is expected to reach $240 billion by 2020. Software is growing faster in the automotive market than it is in smartphones. Hogan quoted a Ford vice president who observed that there are more lines of code in a Ford Fusion car than a Boeing 777 airplane.

One unique challenge for automotive electronics designers is long-term reliability. This is because a typical U.S. car stays on the road for 15 years, Hogan said. Americans are holding onto new vehicles for a record 71.4 months.

Another challenge is regulatory compliance. Aeronautics is highly regulated from manufacturing to air traffic control, and the same will probably be true of automated cars. Hogan speculated that the Department of Transportation will be the regulatory authority for autonomous cars. Today, automotive electronics providers must comply with the ISO26262 automotive functional safety specification.

So where do we go from here? “We’ve got to change our mindset,” Hogan said. “We’ve got to focus on safety and reliability and demand a different kind of engineering discipline.” You can watch Hogan’s entire presentation by clicking on the video icon below, or clicking here.

Hi All,

I have 1 huge project(day X) which has different reference power supply designs.

Now I start a new project and I require 1 specific reference power supply from X.

What is the easist way to do this, other than a copy paste.

Is there a way to create say symbols or something similar, so that multiple different people could use it if they need, in their projects

Thanks for your help and suggestions.

I have been working on a an ASA 17.2 project for the last 6 months.

When I go to Project --> Settings, the settings window does not open. 

The tool indicates that a window is open, as I cannot click on anything else in the project. But it does not show the Settings window.

This has been happening only for the last 2 months. Before that it was working fine.

If I send the project to my colleague, the settings window shows up for him.

Hi, when I applied a voltage divider implemented by two 100-ohm resistors to a 2Vpp 5GHz vsin source, the phase noise simulation using pnoise/fullspectrum with different types, jitter and source have different results. The simulated output noise results are 165.76aV2/Hz for pmjitter case, and 828.79zV2/Hz for source case. The source case result equals to the output noise calculation.

For my application, the output will be applied to driven circuits and thus pm jitter is concerned. As the pmjitter is based on the noise sampling at the threshold crossings, I was wondering how spectre gets the pmjitter resullts since sampling white noise with infinite bandwidth is impossible to my knowledge?

Interestingly, the Jee result by integration from 10kHz to 2.5GHz is ~41fs and is closed to Jee,rms from the transient noise simulation. I am also not sure how these results come and match each other. If applying the voltage divider output to drive next stages, I was wondering to what extent I can trust the input jitter from these simulations? Thank you.

This is the 18th installment of The Rationalist, my column for the Times of India.

The man who gave us our national anthem, Rabindranath Tagore, once wrote that nationalism was “a great menace.” He went on to say, “It is the particular thing which for years has been at the bottom of India’s troubles.”

Not just India’s, but the world’s: In his book The Open Society and its Enemies, published in 1945 as Adolf Hitler was defeated, Karl Popper ripped into nationalism, with all its “appeals to our tribal instincts, to passion and to prejudice, and to our nostalgic desire to be relieved from the strain of individual responsibility which it attempts to replace by a collective or group responsibility.”

Nationalism is resurgent today, stomping across the globe hand-in-hand with populism. In India, too, it is tearing us apart. But must nationalism always be a bad thing? A provocative new book by the Israeli thinker Yael Tamir argues otherwise.

In her book Why Nationalism, Tamir makes the following arguments. One, nation-states are here to stay. Two, the state needs the nation to be viable. Three, people need nationalism for the sense of community and belonging it gives them. Four, therefore, we need to build a better nationalism, which brings people together instead of driving them apart.

The first point needs no elaboration. We are a globalised world, but we are also trapped by geography and circumstance. “Only 3.3 percent of the world’s population,” Tamir points out, “lives outside their country of birth.” Nutopia, the borderless state dreamed up by John Lennon and Yoko Ono, is not happening anytime soon.

If the only thing that citizens of a state have in common is geographical circumstance, it is not enough. If the state is a necessary construct, a nation is its necessary justification. “Political institutions crave to form long-term political bonding,” writes Tamir, “and for that matter they must create a community that is neither momentary nor meaningless.” Nationalism, she says, “endows the state with intimate feelings linking the past, the present, and the future.”

More pertinently, Tamir argues, people need nationalism. I am a humanist with a belief in individual rights, but Tamir says that this is not enough. “The term ‘human’ is a far too thin mode of delineation,” she writes. “Individuals need to rely on ‘thick identities’ to make their lives meaningful.” This involves a shared past, a common culture and distinctive values.

Tamir also points out that there is a “strong correlation between social class and political preferences.” The privileged elites can afford to be globalists, but those less well off are inevitably drawn to other narratives that enrich their lives. “Rather than seeing nationalism as the last refuge of the scoundrel,” writes Tamir, “we should start thinking of nationalism as the last hope of the needy.”

Tamir’s book bases its arguments on the West, but the argument holds in India as well. In a country with so much poverty, is it any wonder that nationalism is on the rise? The cosmopolitan, globe-trotting elites don’t have daily realities to escape, but how are those less fortunate to find meaning in their lives?

I have one question, though. Why is our nationalism so exclusionary when our nation is so inclusive?

In the nationalism that our ruling party promotes, there are some communities who belong here, and others who don’t. (And even among those who ‘belong’, they exploit divisions.) In their us-vs-them vision of the world, some religions are foreign, some values are foreign, even some culinary traditions are foreign – and therefore frowned upon. But the India I know and love is just the opposite of that.

We embrace influences from all over. Our language, our food, our clothes, our music, our cinema have absorbed so many diverse influences that to pretend they come from a single legit source is absurd. (Even the elegant churidar-kurtas our prime minister wears have an Islamic origin.) As an example, take the recent film Gully Boy: its style of music, the clothes its protagonists wear, even the attitudes in the film would have seemed alien to us a few decades ago. And yet, could there be a truer portrait of young India?

This inclusiveness, this joyous khichdi that we are, is what makes our nation a model for the rest of the world. No nation embraces all other nations as ours does. My India celebrates differences, and I do as well. I wear my kurta with jeans, I listen to ghazals, I eat dhansak and kababs, and I dream in the Indian language called English. This is my nationalism.

Those who try to divide us, therefore, are the true anti-nationals. We must reclaim nationalism from them.

This is the 20th installment of The Rationalist, my column for the Times of India.

Amit Shah’s induction into the union cabinet is such an interesting moment. Even partisans who oppose the BJP, as I do, would admit that Shah is a political genius. Under his leadership, the BJP has become an electoral behemoth in the most complicated political landscape in the world. The big question that now arises is this: can Shah do for India what he did for the BJP?

This raises a perplexing question: in the last five years, as the BJP has flourished, India has languished. And yet, the leadership of both the party and the nation are more or less the same. Then why hasn’t the ability to manage the party translated to governing the country?

I would argue that there are two reasons for this. One, the skills required in those two tasks are different. Two, so are the incentives in play.

Let’s look at the skills first. Managing a party like the BJP is, in some ways, like managing a large multinational company. Shah is a master at top-down planning and micro-management. How he went about winning the 2014 elections, described in detail in Prashant Jha’s book How the BJP Wins, should be a Harvard Business School case study. The book describes how he fixed the BJP’s ground game in Uttar Pradesh, picking teams for 147,000 booths in Uttar Pradesh, monitoring them, and keeping them accountable.

Shah looked at the market segmentation in UP, and hit upon his now famous “60% formula”. He realised he could not deliver the votes of Muslims, Yadavs and Jatavs, who were 40% of the population. So he focussed on wooing the other 60%, including non-Yadav OBCs and non-Jatav Dalits. He carried out versions of these caste reconfigurations across states, and according to Jha, covered “over 5 lakh kilometres” between 2014 and 2017, consolidating market share in every state in this country. He nurtured “a pool of a thousand new OBC and Dalit leaders”, going well beyond the posturing of other parties.

That so many Dalits and OBCs voted for the BJP in 2019 is astonishing. Shah went past Mandal politics, managing to subsume previously antagonistic castes and sub-castes into a broad Hindutva identity. And as the BJP increased its depth, it expanded its breadth as well. What it has done in West Bengal, wiping out the Left and weakening Mamata Banerjee, is jaw-dropping. With hindsight, it may one day seem inevitable, but only a madman could have conceived it, and only a genius could have executed it.

Good man to be Home Minister then, eh? Not quite. A country is not like a large company or even a political party. It is much too complex to be managed from the top down, and a control freak is bound to flounder. The approach needed is very different.

Some tasks of governance, it is true, are tailor-made for efficient managers. Building infrastructure, taking care of roads and power, building toilets (even without an underlying drainage system) and PR campaigns can all be executed by good managers. But the deeper tasks of making an economy flourish require a different approach. They need a light touch, not a heavy hand.

The 20th century is full of cautionary tales that show that economies cannot be centrally planned from the top down. Examples of that ‘fatal conceit’, to use my hero Friedrich Hayek’s term, include the Soviet Union, Mao’s China, and even the lady Modi most reminds me of, Indira Gandhi.

The task of the state, when it comes to the economy, is to administer a strong rule of law, and to make sure it is applied equally. No special favours to cronies or special interest groups. Just unleash the natural creativity of the people, and don’t try to micro-manage.

Sadly, the BJP’s impulse, like that of most governments of the past, is a statist one. India should have a small state that does a few things well. Instead, we have a large state that does many things badly, and acts as a parasite on its people.

As it happens, the few things that we should do well are all right up Shah’s managerial alley. For example, the rule of law is effectively absent in India today, especially for the poor. As Home Minister, Shah could fix this if he applied the same zeal to governing India as he did to growing the BJP. But will he?

And here we come to the question of incentives. What drives Amit Shah: maximising power, or serving the nation? What is good for the country will often coincide with what is good for the party – but not always. When they diverge, which path will Shah choose? So much rests on that.

Hi,

I'm doing fault injection with ncsim and got stuck at the following (and not so useful) message: "ncsim: *E,FLTIGF: [FLT] Failed to inject fault at circuit_tb.U0.n2174." I already tried with other NETs, with SET, SA0, SA1, always the same error occurs.

My scripts so far, considering I already compiled the Verilog testbench and also the gates from the technology library (gate-level simulation):

#this runs ok

ncelab -work worklib -cdslib circuit/trunk/backend/synthesis/work/cds.lib -logfile ncelab.log -errormax 15 -access +wc -status -timescale 1ps/1ps worklib.circuit_tb -fault_file circuit/trunk/backend/synthesis/scripts/fi.list

#this runs ok
ncsim -fault_good_run -fault_tw 1ns:4ns -fault_work fault_db -fault_overwrite worklib.circuit_tb:module -input ../scripts/fs_strobe.tcl -exit

#this runs NOT OK
ncsim -fault_sim_run -fault_work fault_db worklib.circuit_tb:module -input ../scripts/injection.tcl -exit

After the above command I get: "ncsim: *E,FLTIGF: [FLT] Failed to inject fault at circuit_tb.U0.n2174."

Here are the files called from the commands above.

fi.list:

fault_target circuit_tb.U0.n2174 -type SET+SA1+SA0

fs_strobe.tcl:

fs_strobe circuit_tb.WRITE_OUT circuit_tb.PC_OUT[0]

injection.tcl:

fault -stop_severity 3 -inject -time 2ns -type sa1 circuit_tb.U0.n2174

I already checked the NETs with simvision, so their paths are correct.

Any ideas?

PS: I know about Xcellium, however, I don't have it yet.

I would like to add these components to the component bank in ORCAD simulation. Even an accessible or free course that explained how to create these components.

Hello All,

I'm currently using OrCAD PCB Designer Professional w/ PSpice (version 16.6-2015).  In the 'Design Object Find Filter' side bar, all options are grayed out and unselectable.  I did attempt to 'Reset UI to Cadence Default' without any luck.  A colleague has no issues with the identical file on his computer.  Any guidance would be much appreciated.  Thanks!
