Most of the time when we blog about upcoming conferences, report live from an ongoing show, or summarize one that’s just finished, we see a significant spike in readership. Clearly our followers want to keep up with what’s happening in trade shows, conferences, and other industry events. It may also be the case that tighter travel budgets have reduced the ability to attend conferences in person, driving all the more interest in reading the news from the field. A few weeks ago, we discussed DesignCon and explained how it had evolved to include almost no verification content.
Next week is the annual Design and Verification Conference (DVCon) in San Jose, an event that we have covered in considerable detail in several popular posts in the past. As we have discussed, this conference has become the main way to keep up on what’s happening in the ever-changing world of functional verification. We encourage you to check out their Web site and the complete program. The topics include the UVM, SystemVerilog, SystemC, code generation, multi-language, mixed-signal, formal techniques, coverage metrics, and low-power verification.

In any industry dominated by a few large companies, it is important for the smaller players to ensure that their products work well with the broader solutions from the majors. Recognizing this need, and sometimes encouraged by legal action, the large companies develop partnership programs to enable and even foster integration with their solutions. All this is true for the EDA business, where the “Big 3” work closely with many smaller vendors for the sake of their mutual customers.
In Breker’s case, we generate SoC test cases that run on a variety of software and hardware platforms. We do not build any of those platforms ourselves but we need to verify that our test cases can run properly on them. Accordingly, we are members of several important partnership programs and we work closely with other vendors to find and fix any interoperability issues before our customers run into them. In this week’s post, we focus on how we work with Synopsys, the EDA market leader.

As you may have seen this morning, the EDA standards organization Accellera officially announced the formation of the Portable Stimulus Working Group (PSWG). This group has the charter to “develop the electronic industry’s first standard for portable test and stimulus. When completed and adopted, this standard will enable a single specification that will be portable from IP to full system and across multiple target implementations.”
Regular readers will note that this wording sounds very familiar. At Breker, we’ve been talking about vertical reuse from IP to SoC and horizontal reuse across all verification platforms for years. At times we’ve felt like pioneers with arrows in our back. The formation of the PSWG is a validation that we’ve been heading in the right direction. We’re excited to see the industry embracing the challenges of SoC verification and starting to work on a new standard to address these challenges.

Two recent blog posts discussed what you should run when you first map your system-on-chip (SoC) design into an emulation platform and when you have your first fabricated chips from the foundry in your bring-up lab. We pointed out that trying to boot an operating system and run applications should not be the first step because production software is not designed to find and debug lingering hardware design errors. We recommended running the multi-threaded, multi-processor, self-verifying C test cases generated and optimized for hardware platforms by our TreSoC-Si product.
As you may know, TrekSoC uses the same graph-based scenario models as TrekSoC-Si, but optimizes the generated test cases for virtual prototypes, simulation, and simulation acceleration. In this post, we ask a similar question: what should you run in simulation when you first have the RTL for your SoC assembled and ready to be verified? Of course our answer will be the test cases generated by TrekSoC. However, there are some advantages of simulation over hardware platforms that foster a more extensive methodology for verification with Breker’s products.
