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...

Tales from DAC: A Meeting of Security's Heroes at the Accellera Luncheon (Part 2 of 2)

By XTeam | 25 Jun 2019

Welcome back to this account of the IP Security Panel at the Accellera Luncheon at DAC 2019. We’ve covered who’s seated on the panel and the moderator’s questions in the last installment (link to first blog)—now it’s time to talk about what the audience had to ask. The first question asked was related to that morning’s keynote speaker, and that speaker’s one criteria for IP developers with regards to security: do they...

Tales from DAC: A Meeting of Security's Heroes at the Accellera Luncheon (Part 1 of 2)

By XTeam | 24 Jun 2019

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. The often-joked-about case of someone hacking your refrigerator isn’t strictly a joke—without...

Specman: Python Is here!

By teamspecman | 12 Jun 2019

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...

Concurrent Actions in Specman: Part 2

By teamspecman | 8 May 2019

In the previous blog: Concurrent Actions in Specman , we discussed the existing options: all of ( which awaits completion of all branches) and first of (which terminates at the first completion of any branch). In 19.03 we added enhancement on top of these existing options, we made them more dynamic. In all the examples in the previous blog, the number of branches was constant (all the examples used 2 branches). What...

Specman Linting and the all_unique Method

By teamspecman | 29 Apr 2019

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...

Concurrent Actions in Specman

By teamspecman | 25 Mar 2019

Lately we have been asked by several customers about the concurrency options in Specman (some refer to it as “What are the Specman options similar to fork…join?”). Apparently, things that are in Specman for ages are likely to be missed. Therefore, this blog describes Specman concurrent actions (existing for years). Specman has two actions controlling concurrent execution: all of and first of. Both actions create parallel...
