Preview of an Exciting New Show: DVCon India

Friday, August 29th, 2014

As anyone involved in chip development knows, one of the biggest events of the year is the Design and Verification Conference and Exhibition, DVCon, which has been held for many years in San Jose. I’ve frequently shared my thoughts on this show and its importance to the industry in this blog. In just four weeks, DVCon expands to Bangalore for the very first DVCon India show. The full program for September 25-26 is now online and I’d like to focus on a few highlights from my perspective.

The first thing to note is the breadth of material being covered. The technical track is split between electronic system level (ESL) and design and verification (DV) topics, with a slight edge to the latter in terms of overall sessions. There are as many as five tracks in parallel, which is quite an accomplishment for a brand-new event. I know that there were many excellent session proposals submitted, which means that those selected are likely to be of high quality and wide interest.


Composition, Chaining, and Vertical Reuse with TrekUVM

Wednesday, August 20th, 2014

Several posts back, we introduced the idea of “composing” higher-level verification elements from low-level elements with little or no effort. We discussed how this was not possible with traditional testbench elements such as virtual sequencers and scoreboards. We showed that Breker’s graph-based scenario models can be simply combined from the block level to the cluster level, and from the cluster level to the full-chip level.

Last week, we took the unusual step of announcing a new EDA product via social media rather than a traditional press release. The news about TrekUVM clearly spread; we had a nice spike in blog readership and an even bigger spike in traffic to our Web site. Since our readers have interest in this new product, we’d like to continue talking about it and, specifically, show how it fosters model composition and vertical reuse.


Introducing TrekUVM: Enhancing Transactional UVM Testbenches

Thursday, August 14th, 2014

In our previous four posts, we have woven a story quite different from the way we’ve talked about Breker and our technology for the past few years. Regular readers know that our focus has been on verifying system-on-chip (SoC) designs by generated multi-threaded, self-verifying C test cases to run on the SoC’s embedded processors. TrekSoC generates these test cases for simulation with RTL or ESL models; TrekSoC-Si generates test cases for emulator, FPGA prototypes, and actual silicon.

The last few posts have pointed out that TrekSoC has had to handle running in a transactional testbench since many test cases send data on or off the chip. We’ve worked hard to ensure that we can integrate easily into testbenches compliant with the Universal Verification Methodology (UVM) standard. Today we leverage this knowledge as we introduce TrekUVM, which generates multi-threaded, self-verifying test cases for a purely transactional UVM testbench.


Transactional Design Verification with TrekSoC

Thursday, August 7th, 2014

In our last blog post, we worked our way up the conclusion that our TrekSoC product can be used to verify designs that do not contain embedded processors. As we noted, there is not a widely accepted industry term for such devices. For the moment, let’s call them “transactional designs” since the majority of them take transactions in at one end and generate transactions at the other end, sometimes for two very different protocols, and are often bidirectional in nature.

The technological argument is simple. Most SoCs also have I/O ports, both standard buses and proprietary protocols, and TrekSoC must be able to talk to them, coordinate among them, and synchronize their transactions with generated C code running in the embedded processors. A purely transactional chip and testbench form a subset of the challenge for which TrekSoC is designed, so it’s not surprising that we can help. Today’s post fills in some more details.
