Narendra Modi’s request was simple: to help combat the spread of coronavirus, people should download an Indian government-built smartphone app that helps identify their risk of catching and spreading the virus.

“As more and more people use it, its effectiveness will increase,” the prime minister said in a televised address last month.

Verifying lane adapter state machine in a router design is quite an involved task and needs verification from several aspects including that for its link training functionality.

The diagram below shows two lane adapters connected to each other and each going through the link training process. Each training sub-state transition is contingent on conditions for both transmission and reception of relevant ordered sets needed for a transition. Until conditions for both are satisfied an adapter cannot transition to the next training sub-state.

As deduced from the lane adapter state machine section of USB4 specification, the reception condition for the next training sub-state transition is less strict than that of the transmission condition. For ex., for LOCK1 to LOCK2 transition, the reception condition requires only two SLOS symbols in a row being detected, while the transmission condition requires at least four complete SLOS1 ordered sets to be sent.

From the above conditions in the specification, it is a possibility that a lane adapter A may detect the two SLOS or TS ordered sets, being sent by the lane adapter B on the other end, in the very beginning as soon as it starts transmitting its own SLOS or TS ordered sets. On the other hand, it is also a possibility that these SLOS or TS ordered sets are not yet detected by lane adapter A even when it has met the condition of sending minimum number of SLOS or TS ordered sets.

In such a case, lane adapter A, even though it has satisfied the transmission condition cannot transition to the next sub-state because the reception condition is not yet met. Hence lane adapter A must first wait for the required number of ordered sets to be detected by it before it can go to the next sub-state. But this wait cannot be endless as there are timeouts defined in the specification, after which the training process may be re-attempted.

This interlocked way of operation also ensures that state machine of a lane adapter does not go out of sync with that of the other lane adapter. Such type of scenarios can occur whenever lane adapter state machine transitions to the training state from other states.

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.

First, the good news. The EDA industry will grow from $6.2 billion in 2015 to $9.0 billion in 2019, according to Gary Smith, chief analyst at Gary Smith EDA. Year-to-year growth rates will range from +4% to +11.2%.

But in his annual presentation on the eve of the Design Automation Conference (DAC 2015), Smith noted that Wall Street is unimpressed. “The people I talk to want long-term steady growth, no sharp up-turns, no sharp downturns,” Smith said. “To the rest of Wall Street, we’re boring.”

Smith spent the rest of his talk noting how EDA can be a lot less boring and, potentially, a whole lot bigger. For starters, what if we add semiconductor IP to EDA revenues? Now we’re looking at $12.2 billion in revenue by 2019, Smith said. (He acknowledged, however, that the IP market itself is going to take a “dip” due to the move towards platform-based IP and away from conventional piecemeal IP).

This still is not enough to get Wall Street’s attention. Another possibility is to bring embedded software development into the EDA industry. This is not a huge market – about $2.6 billion today – but it is an “easy growth market for us,” according to Smith.

Chasing the Big Bucks

But the “big bucks” are in mechanical CAD (MCAD), Smith said. In the past the MCAD market has always been bigger than EDA, but now EDA is catching up. The MCAD market is about $6.6 billion now. Synopsys and Cadence are larger than PTC and Siemens, two of the main players in MCAD.

There may be some good acquisition possibilities coming up for EDA vendors, Smith said – and if we don’t buy MCAD companies, they might buy EDA companies. Consider, for example, that Ansoft bought Apache and Dassault bought Synchronicity. (Note: Siemens PLM Software is a first-time exhibitor at DAC 2015).

What about other domains? Smith said that EDA companies could conceivably move into optical design, applications development software, biomedical design, and chemical design. The last if these is probably the most tenuous; Smith noted that EDA vendors have yet to look into chemical design.

Applications development software is the biggest market on the above list, but that means competing with Microsoft, IBM, and Oracle. “You’re in with the big boys – is that a good idea?” Smith asked.

Perhaps there’s an opening for a “big play” for an MCAD provider. Smith noted that mechanical vendors are focusing on product data management (PDM). This “is really the IT of design,” Smith said. “They have a lot of hope that the IoT [Internet of things] market is going to give them an opportunity to capture the software that goes from the ground to the cloud. Maybe we can let them have PDM and see if we can take the tool market away from them, or acquire it away from them.”

In conclusion, Smith asked, should the EDA industry accelerate its growth? “The mechanical vendors have already shown interest in acquiring EDA vendors,” he said. “We may not have a choice.”

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.
