Troubleshooting Xcelium Errors/Warnings with xmhelp/xmbrowse and Cadence Support Portal

By SumeetAggarwal | 17 Jul 2020

I joined Cadence in July 2000 and was immediately put on a three-month training to learn and understand the simulator tools. There were formal training sessions, and I had a mentor whom I could ask all my queries. But most of the time, I was on my own, as "learning by doing" was the motto of my mentor. Today, after completing 20 years at Cadence, I can tell you that it works great, especially in cases where the tool...

Improving Tests Efficiency Using Coverage Callback (part 2)

By teamspecman | 28 Jun 2020

In recent blogs - specman-callback-coverage-api and improving-tests-efficiency-using-coverage-callback - we shared some ideas about how to employ the new Coverage Callback API for increasing the tests efficiency. This blog shows two more ideas for improving tests, using runtime coverage information. Stop the Run After the Goal Is Reached The basic concept of Coverage Driven Verification is running many random tests...

Training Insights - Comprehensive RTL Signoff Using JasperGold Superlint App

By Nizar Hanna | 15 Jun 2020

Most have heard the phrase "time is money". Thinking more about it, probably the right phrase would be "time is more valuable than money". People look at their bank accounts with great attention but don't tend to look at their time the same way, ending up wasting this greatly valuable and important resource. You can gain money using time, but you can’t use money to purchase more time. The “Shift Left” concept has been...

Improving Tests Efficiency Using Coverage Callback

By teamspecman | 31 May 2020

When you go to the store, you walk until you get there, stop, get your groceries, and go back home. You do not start circling around the block for few rounds. You do not say “if I walk around the block really fast, I can save time”. It is clear that if you avoid circling the block at first place – you will save even more time. Why don’t we adopt the same rationale in the verification process? Instead of thinking just...

Specman’s Callback Coverage API

By teamspecman | 30 Apr 2020

Our customers’ tests have become more complex, longer, and consume more resources than before. This increases the need to optimize the regression while not compromising on coverage. Some advanced customers of Specman use Machine Learning based solutions to optimize the regressions while some use simpler solutions. Based on a request of an advanced customer, we added a new Coverage API in Specman 19.09 called Coverage...

Metamorphic Testing: The Future of Verification?

By XTeam | 16 Apr 2020

Curious about what’s going on behind the scenes with verification? Bernard Murphy, Jim Hogan, and our own Paul Cunningham are on the case with the “Innovation in Verification” blog stream over at semiwiki.com . Every month, this trio reviews a newly-published paper in academia that pertains to verification and discusses its implications. Be sure to stop by—it’s a great place to see what might be coming down the pipeline...

Specman: Analyze Your Coverage with Python

By teamspecman | 6 Nov 2019

In the former blog about Python and Specman: Specman: Python Is here! , we described the technical information around Specman-Python integration. Since Python provides so many easy to use existing libraries in various fields, it is very tempting to leverage these cool Python apps. Coverage has always been the center of the verification methodology, however in the last few years it gets even more focus as people develop...

Automotive Security in the World of Tomorrow - Part 2 of 2

By XTeam | 22 Aug 2019

If you missed the first part of this series, you can find it here . So: what does Green Hills Software propose we do? The issue of “solving security” is, at its core, impossible—security can never be 100% assured. What we can do is make it as difficult as possible for security holes to develop. This can be done in a couple ways; one is to make small code in small packs executed by a “safing plan”—having each individual...

Automotive Security in the World of Tomorrow - Part 1 of 2

By XTeam | 21 Aug 2019

Autonomous vehicles are coming. In a statistic from the U.S. Department of Transportation , about 37,000 people died in car accidents in the United States in 2018. Having safe, fully automatic vehicles could drastically reduce that number—but the trick is figuring out how to make an autonomous vehicle safe. Internet-enabled systems in cars are more common than ever, and it’s unlikely that the use of them will slow or...

Tales from DAC: Altair's HERO Is Your Hero

By XTeam | 29 Jul 2019

Emulators are great. They vastly speed up verification to the point where it’s hard to imagine life without them; as designs grow in complexity, simple simulation can’t keep up for the biggest designs. The extra oomph from emulation is almost a necessity for the top percentages of design sizes. However, many users of Palladium aren’t efficiently using their unit’s processing power, and as a result they’re missing out...

Tales from DAC: Semiconductor Design in MY Cloud? It's More Likely Than You Think

By XTeam | 24 Jul 2019

Everyone keeps talking about “the cloud” this and “the cloud” that these days—but you’re a semiconductor designer. Everyone keeps saying “the cloud” is revolutionizing all aspects of electronics design—but what does it mean for you? Cadence's own Tom Hackett discussed this in a presentation at the Cadence Theater during DAC 2019. What people refer to as “the cloud” is commonly divided into three categories: Infrastructure...

Figure 1: The panel and crowd Citizens—the tech world is in trouble. With the ever-expanding size and complexity of chip designs, security hasn’t kept up. Old techniques for securing a design are no longer sufficient—and with IoT devices expanding into every facet of a person’s life, security is more important than ever.

Specman: Python Is here!

Do you know from where Python technology gets its name? It is not from the snake, it is named after the Monty Python comedy group. And indeed, one of the main guidelines behind it is to be fun to use (check out the Zen of Python ). Therefore, Python is intuitive, readable, and easy to learn - all of these make it not only fun to use but also highly productive. Does this sound familiar? If you are an e user, it should...

Specman Linting and the all_unique Method

Sorting according to pointers- why? One of the best practices that you need to follow when using Specman or any other tool is to use a linting tool on a regular basis to catch bugs early. In Specman, we frequently add additional e checks to HAL (Cadence linting tool) based on the customer issues that can be avoided or caught during linting. For instance, in 19.03, among few other linting checks, we planned to add...
