Hi,

I am trying to write a skill code where it takes form inputs by default and just displays tree directly.

i have written below code,

procedure( create_tree()
let(()

leHiTree()
leTreeForm->treeOption->value="Current to user level"
leTreeForm->userLevel->value= 31
ipcSleep(1)
hiFormDone(leTreeForm)

))

the form takes in values but it is not closing.

tried with regtimer in place of ipc sleep, didn't work.

how to close form(should be same as pressing OK)? 

Thanks in advance,

Hi,

I want to convert ircx file(which is from TSMC,inclued EM Information) to ict or emDataFile for Voltus-fi.

I tried many way, but I can not make it. Can anyone give me some advice?

and I  do not installed QRC.

below is some tools installed my server. 

IC617-64b.500.21 is used.

Hello,

I have created an appForm with  the following attachmentList and size:

?attachmentList list(hicLeftPositionSet | hicRightPositionSet ; field 1
                     hicLeftPositionSet | hicRightPositionSet ; field 2
etc.

?initialSize    800:800
?minSize        800:800
?maxSize       1600:800

If I reduce the minimum y-size (?minSize        800:200), scrollbars are not inserted, unless I remove the attachmentList constraints.

Is it possible to have both scrollbars and "hicLeftPositionSet | hicRightPositionSet"? 

Thank you,

Best regards,

I can get the bound stdcells using bndGetBoundObjects, but not get what each individual stdcell corresponds in layout.

Is there a way to get the layout bound stdcells of an array schematic symbol if the layout stdcell name do or do not match the symbol naming?

Once the schematic array stdcells are bound to the layout stdcells, how to get the correct terminal term~>name and net~>name?

Example of a schematic symbol and layout stdcell:

Schematic

INV<0:2>    instTerms~>terms~>name = ("vss" "vdd" "A" "Y")

                   instTerms~>net~>name = ("<*3>vss" "<*3>vdd" "in<0:2>" "nand2A,nand3B,nor2B")

Layout ( I know it is bad practice, but it happens )

stdcell1 instTerms~>terms~>name = ("vss" "vdd" "A" "Y")

             instTerms~>net~>name = ("vss" "vdd" "in<0>" "nand2A")

I23        instTerms~>terms~>name = ("vss" "vdd" "A" "Y")

             instTerms~>net~>name = ("vss" "vdd" "in<1>" "nand3B")

INV(2) instTerms~>terms~>name = ("vss" "vdd" "A" "Y")

             instTerms~>net~>name = ("vss" "vdd" "in<2>" "nor2B")

We're happy to have guest blogger Thorsten Dworzak, Principal Consultant at Verilab GmbH, describe how he added Specman/e syntax to Sublime Text 3:

According to the 2018 StackOverflow Developer Survey, the popularity of development environments (IDEs, Text Editors) among software developers shows the following ranking:

1. Visual Studio Code 34.9%
2. Visual Studio 34.3%
3. Notepad++ 34.2%
4. Sublime Text 28.9%
5. Vim 25.8%
6. IntelliJ 24.9%
7. Android Studio 19.3%
8. (DVT) Eclipse 18.9%
9. …

15. Emacs 4.1%

Of these, only Vim, (DVT) Eclipse, and Emacs support editing in e-language (at least, last time I checked). Kate, which comes with KDE and also has a Specman mode, is not on this list.

I started using Sublime Text 3 some time ago. It offers packages that support a number of programming languages.

Though there is an e-language syntax available from Tsvi Mostovicz, it is unfinished work, and there are many syntactic constructs are missing. So, I created a fork of his project and finished it (it will eventually be merged back here).

It is a never-ending task because my code base for testing is limited and e is still undergoing development. The project is available through ST3's Package Control and you can contribute to it via Github.

I am eagerly waiting for your pull requests and/or comments and contributions!

On May 7, 2013 Cadence announced a 30% productivity gain in the June 2013 Incisive Enterprise Simulator 13.1 release.  Advanced debug visualization, faster turn-around time, and the extension of eight years of low-power verification innovation to IEEE 1801/UPF are the key capabilities in the release.

When we talk about low-power verification its easy to equate it with simulation.  For certain, simulation is the heart of a low-power verification solution. Simulation enables engineers to run their design in the context of power intent.  The challenge is that a simulation-only approach is inadequate. For example, if engineers could achieve SoC quality by verifying the individual function of each power control module (PCM), then simulation could be enough.  For a single power domain, simulation can be enough. 

However, when the SoC has multiple power domains -- and we have seen SoCs with hundreds of them -- engineers have to check the PCMs and all of the arcs between the power modes.  These SoCs often synchronize some of the domain switching to reduce overall complexity, creating the potential for signal skew errors on the control signals for the connected domains.  Managing these complexities requires verification methodologies including advanced debug, verification planning, assertion-based verification, Universal Verification Methodology - Low Power (UVM-LP), and more (see Figure 1).

Figure 1:  Comprehensive Low-Power Verification 

But even advanced verification methodologies on top of simulation aren't enough.  For example, the state machine that defines the legal and illegal power mode transitions is often written in software. The speed and capacity of the Palladium emulation platform is ideal to verify in this context, and it is integrated with simulation sharing debug, UVM acceleration, and static checks for low-power. And, it reports verification progress into a holistic plan for the SoC.  Another example is the ability to compare the design in the implementation flow with the design running in simulation to make sure that what we verify is what we intend to build.

Taken together, verification across multiple engines provides the comprehensive low-power verification needed for today's advanced node SoCs.  That's the heart of this low-power verification announcement. 

Another point you may have noticed is the extension of the Common Power Format (CPF) based power-aware support in the Incisive Enterprise Simulator to IEEE 1801.  We chose to bring IEEE 1801 to simulation first because users like you sometimes need to mix vendors for regression flows.  Over time, Cadence will extend the low-power capabilities throughout its product suite to IEEE 1801.

If you are using CPF today, you already have the best low-power solution. The evidence is clear:  the upcoming IEEE 1801-2013 update includes many of the CPF features contributed to 1801/UPF to enable methodology convergence.  Since you already have those features in the CPF flow, any migration before you have a mature IEEE 1801-2013 tool flow would reduce the functionality you have today.

If you are using Unified Power Format (UPF) 1.0 today, you want to start planning your move toward the IEEE 1801-2013 standard.  A good first step would be to move to the IEEE 1801-2009 standard.  It fills holes in the earlier UPF 1.0 definition.  While it does lack key features in -2013, it is an improvement that will make the migration to -2013 easier. The Incisive 13.1 release will run both UPF 1.0 and IEEE 1801-2009 power intent today.

Over the next few weeks you'll see more technical blogs about the low-power capabilities coming in the Incisive 13.1 release.  You can also join us on June 19 for a webinar that will introduce those capabilities using the reference design supplied with the Incisive Enterprise Simulator release.

Hello,

Would anyone know how to setup a PSS or QPSS simulation with 25% dutycycle clock sources or if such a thing is possible with QPSS.

Fig1 (below) is a snapshot of the circuit I am trying to characterize. This has 4 clock ports each with 25%duty cycle in the ON state. Fig2 below shows two of these clocks.

Each path in the circuit consists of two switches with a low pass RC sandwiched in between. The Input is a 50Ohm port sine wave and the output is a 1K resistor. The output nets of all paths are connected together.

I am trying to determine the swept frequency response from input to output (voltage) when the input is from 500Mhz to  510MHz. The Period (T=1/Fp) of each of the pulses is such that Fp=500MHz. The first pulse source has a delay=0, second has delay=T/4, third delay=2T/4, etc...

I am currently getting it working and seeing the correct result (bandpass response) with Transient but the problem is doing a dft at 500MHz with 10KHz spacings needs at least 100us and takes up a lot of time and disk space.

Many Thanks,
Chris.

Hello, I have a problem with a certain type of transistor,my hyrarchy has a lot components an sub components and visually inspecting them is very hard.

is there a way like in other cadence layout viewer tools , to enter the name of the component or a NET somewhere and it will focus on it visualy or give the hyrarchy path to it?

Thanks.

Hi Guys,

Anyone know equivalent skill for create detail.

Eugene

hello there, i'm a student studying allegro PCB designer.

There are some commands that i can do with GUI, but i want to know what kind of commands i used so that i can route with commands only(ex) skill).

Is there any file that i can see what kind of commands i used something like log files or command history?

thank you for reading this long boring question.

I have a script to handle many polys in memory in allegro. 

But after the completion of the script, 

I run the axlPolyMemUse(), it reports (31922 0 0 55076 252482)

Seems too many polys are still in the memory，and they are not being used. 

So how to delete these polys from the memory? And reclaim the memory?

BTW. I have no skill dev license. So gc() function doesn't work. 

Thanks.

I'm working on a circuit that requires the input voltage to be converted to a frequency, transmitted over an optical cable, and then converted back to a voltage. I am attempting to simulate this circuit using Eagle ngSpice simulations. The voltage to frequency converters that I am using are ADVFC32 and made by Analog Devices. However, I can't seem to find a SPICE model for this component. Analog Devices does not provide it on their website. Can anyone find a SPICE Model for this part? I'm new to working with electronics so any help/advice you can provide would be appreciated.

I have made a customized menu in PCB Editor which I now would like to fill with content.

First of all I would like to have commands to add (or delete) layers in the board. I have parameter files (.prm) that describes both the stackup and the artwork for 2, 4, 6 and 8 layers.

I guess I could record a script (macro) where I use the "Import Parameter file" dialogue but this will get windows flickering by etc. Can I do this with SKILL instead?

I realize that it is possible (somehow) to do a SKILL-script that completely builds up the stackup and artworks for boards with different number of layers but I then have to edit the SKILL everytime I need to change anything. My thinking is that it perhaps is easier just to call the prm-file, which is easy to modify from within Allegro without knowing anything about SKILL.

I'm also looking for a solution to remove some Subclasses, containing certain keywords with a SKILL script but since I'm completely new to SKILL I don't really know where to begin.

Any assistance would be much appreciated.

Hi,

I wanted to find the location of a pin in the design using skill program. pin_dbids = axlDBGetDesign()->pins, this gives me all the dbids of the pins that are present in my design. But when im entering that dbid, pad = axlDBGetPad("000001EA8FD8B9F8" "package geometry/assembly_top" "regular") it is throwing an error stating "This dbid is not user defined. Please enter the user defined". So please provide me a snippet so that I can get the exact pin location in the design using skill script.

Hello All,

Is there a SKILL function to obtain the Form path (similar to getSkillPath).

If not, is the a workaround to obtain the Form path?

Thanks All

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.

This is the 24th installment of The Rationalist, my column for the Times of India.

Back in the last decade, I was a cricket journalist for a few years. Then, around 12 years ago, I quit. I was jaded as hell. Every game seemed like déjà vu, nothing new, just another round on the treadmill. Although I would remember her fondly, I thought me and cricket were done.

And then I fell in love again. Cricket has changed in the last few years in glorious ways. There have been new ways of thinking about the game. There have been new ways of playing the game. Every season, new kinds of drama form, new nuances spring up into sight. This is true even of what had once seemed the dullest form of the game, one-day cricket. We are entering into a brave new world, and the team leading us there is England. No matter what happens in the World Cup final today – a single game involves a huge amount of luck – this England side are extraordinary. They are the bridge between eras, leading us into a Golden Age of Cricket.

I know that sounds hyperbolic, so let me stun you further by saying that I give the IPL credit for this. And now, having woken up you up with such a jolt on this lovely Sunday morning, let me explain.

Twenty20 cricket changed the game in two fundamental ways. Both ended up changing one-day cricket. The first was strategy.

When the first T20 games took place, teams applied an ODI template to innings-building: pinch-hit, build, slog. But this was not an optimal approach. In ODIs, teams have 11 players over 50 overs. In T20s, they have 11 players over 20 overs. The equation between resources and constraints is different. This means that the cost of a wicket goes down, and the cost of a dot ball goes up. Critically, it means that the value of aggression rises. A team need not follow the ODI template. In some instances, attacking for all 20 overs – or as I call it, ‘frontloading’ – may be optimal.

West Indies won the T20 World Cup in 2016 by doing just this, and England played similarly. And some sides began to realise was that they had been underestimating the value of aggression in one-day cricket as well.

The second fundamental way in which T20 cricket changed cricket was in terms of skills. The IPL and other leagues brought big money into the game. This changed incentives for budding cricketers. Relatively few people break into Test or ODI cricket, and play for their countries. A much wider pool can aspire to play T20 cricket – which also provides much more money. So it makes sense to spend the hundreds of hours you are in the nets honing T20 skills rather than Test match skills. Go to any nets practice, and you will find many more kids practising innovative aggressive strokes than playing the forward defensive.

As a result, batsmen today have a wider array of attacking strokes than earlier generations. Because every run counts more in T20 cricket, the standard of fielding has also shot up. And bowlers have also reacted to this by expanding their arsenal of tricks. Everyone has had to lift their game.

In one-day cricket, thus, two things have happened. One, there is better strategic understanding about the value of aggression. Two, batsmen are better equipped to act on the aggressive imperative. The game has continued to evolve.

Bowlers have reacted to this with greater aggression on their part, and this ongoing dialogue has been fascinating. The cricket writer Gideon Haigh once told me on my podcast that the 2015 World Cup featured a battle between T20 batting and Test match bowling.

This England team is the high watermark so far. Their aggression does not come from slogging. They bat with a combination of intent and skills that allows them to coast at 6-an-over, without needing to take too many risks. In normal conditions, thus, they can coast to 300 – any hitting they do beyond that is the bonus that takes them to 350 or 400. It’s a whole new level, illustrated by the fact that at one point a few days ago, they had seven consecutive scores of 300 to their name. Look at their scores over the last few years, in fact, and it is clear that this is the greatest batting side in the history of one-day cricket – by a margin.

There have been stumbles in this World Cup, but in the bigger picture, those are outliers. If England have a bad day in the final and New Zealand play their A-game, England might even lose today. But if Captain Morgan’s men play their A-game, they will coast to victory. New Zealand does not have those gears. No other team in the world does – for now.

But one day, they will all have to learn to play like this.

Hi all,

I would like to understand if it is possible from Simvision to get the information regarding the view of a block. In principle using the Schematic Tracer Simvision is able to find the information about the config of that particular model, but I did not found a command for describing the nature of the module (for example if it is schematic or rtl or real model...)

Any functions that I can use for this purpose?

Many thanks

I'm sending encrypted HDL to a customer who will use Cadence IES for simulation and was wondering how I should go about the encryption.

Does IES support the IEEE's P1735 and if so, where can I find Cadence's public key for performing the encryption?

Or is there an alternative solution that I can use for encryption?

Hi all,

         I want to know how to run a regressive test in cadence and merge all ncsim .trn file of each test case into a single file to view all waveform in simvision. I am using Makefile to invoke the test case.

         eg:-

               test0:

                     irun -uvm -sv -access +rwc $(RTL) $(INTER) $(PKG) $(TOP) $(probe) +UVM_VERBOSITY=UVM_MEDIUM +UVM_TESTNAME=test0

             test1:

                   irun -uvm -sv -access +rwc $(RTL) $(INTER) $(PKG) $(TOP) $(probe) +UVM_VERBOSITY=UVM_MEDIUM +UVM_TESTNAME=test1

          I just to call test0 followed by test1 or parallel both test and view the waveform for both tests case.

        I new to this tool and help me with it

xmsim is not exiting the simulation for this error. It is unusual for the simulator to not exit for an error. I have just started using uvm and this is occurring during the randomization step for a sequencer item.

xmsim: *E,RNDCNSTE

I am using -EXIT on the command line.

I am using Xcelium 19.03-s013.

Any insights are appreciated. Thanks.

Specman *search* command allows searching in all loaded modules, but only for a string.

Is there a way to search for a regexp or glob?

Alternatively, is there a way to simply get a list of all loaded files somehow? Then I could use either the "shell" command, or real shell together with grep.

Thanks

When I run simulation with irun, it may use may license features. How can I know which feature(s) a product use? I get below message in cdnshelp:

-------------------------------------------------------------

Which Products Are in the License File?

One Cadence product can require more than one license (FEATURE). The product to feature mapping in the license file lists the licenses each product needs.

For example, if the license file lists these features for the NC-VHDL Simulator:

Product Name: Cadence(R) NC-VHDL Simulator
#
Type: Floating Exp Date: 31-jul-2006 Qty: 1
#
Feature: NC_VHDL_Simulator [Version: 9999.999]
#
Feature: Affirma_sim_analysis_env [Version: 9999.999]

-------------------------------------------------------------------

But, in my license file, I can't find such info. There is only "FEATURE" lines in my license file. How can I get product to feature mapping info?

Thanks!

Variants seem to be defined as present or not present.

Is there a variant that can assign different parts to the same reference designator? i.e.  R17 can be either 0 ohm 0805 jumper or 12k ohms 0805 resistor.

The simplest way I can think of is to use two parts with the same footprint and overlay them.

Is there a more functional way of doing this?  So that the variant would put the correct part in the BOM and the parts would of course have the same identical footprint.

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.

Please include a brief summary of how to use it.

Hi, I am uploading a register class, which can be used for modeling hardware registers. I am uploading the source code and examples on how to run it. I also have a user guide which has all the APIs listed and explained. The user guide is ARV.pdf in the attached tar file. I have named the class ARV, which stands for Architect's Register View. It has got very good randomization and coverage features. Users have told me that its better than RAL. You can download it from http://verisilica.info/ARV.php
. There is a limit of 750KB in this cadence website. The ARV file is 4MB. That is why, I am uploading it at this site. I have a big pdf documentation and a doxygen documentation there. That is the reason for the bigger file size. The password to open the ZIP file is ovm_arv. I hope, everyone will use these classes.

Please contact me for any help.

In a nutshell, tags allows you to navigate through program code distributed over multiple files effectively. e.g if you see a function call or a struct in e-code and want to "jump" to the definition (which may be in a different file) then you just hit CTRL+] in Vim! Pressing CTRL+t will take you back where you came from. Check out http://vim.wikia.com/wiki/Browsing_programs_with_tags#Using_tags if you want to learn more about how to use tags with Vim.

This utility can generate tags file for your e files. It can either walk through e import order, a directory recursively or all directories on SPECMAN_PATH recursively! The tags file will have tags for struct, unit, types, events, defines, fields, variables, etc.

For help and some examples, just run ctags4e -help.
