Verification Needed to Take High-Level Synthesis Mainstream

Tuesday, December 2nd, 2014

This blog focuses mostly on verification, but from time to time we like to take a look at other aspects of the EDA industry. Today we’d like to discuss high-level synthesis (HLS), its progress and status, and what’s keeping it from being  a mainstream technology used for every chip design. It turns out that this topic has a lot to do with verification, so we’re not straying too far from our primary focus.

To start, let’s define what we mean by HLS in contrast to the mainstream technology of logic synthesis. Generating gates from a hardware description language (HDL) moved from a research problem to viable products around 1988. The ultimate winner among several promising companies was Synopsys, in part because they chose a register-transfer level (RTL) subset of the popular Verilog HDL as their input format. Their tools generated a gate-level netlist using the cells available in an ASIC vendor’s library.

April 21, 2014: A-Day for Formal Analysis

Tuesday, April 22nd, 2014

Yesterday may well go down in EDA history as one of the most important days in the evolution of the market for formal analysis. If you had asked me why yesterday morning, I would have said it was because I was attending the third “Decoding Formal Club” meeting sponsored by formal consulting experts Oski Technology. The range of companies represented there, and the enthusiasm for the topic, was a clear indication that formal has become an A-list technology for many verification teams.

So I planned to write today’s post about this meeting. But then, just as it was ending and Oski was thanking all the participants, news broke that Cadence had acquired formal leader Jasper Design Automation for $170M. Of course, this news was of intense interest to the attendees. It made yesterday “Acquisition Day” for formal analysis, so I’ll dub it “A-Day” and provide some thoughts in this post. I will talk a bit about the meeting as well, but will go into more details about the material presented in a future post.

Guest Post: OneSpin’s Successful Return to DAC

Tuesday, July 9th, 2013

As you have read, Breker had an excellent Design Automation Conference (DAC) this year. Many other EDA vendors were pleased as well. Today, guest blogger Dr. Raik Brinkmann from OneSpin Solutions shares his experience:

After sitting out DAC last year, OneSpin Solutions was back, exhibiting and demonstrating our innovative formal assertion-based verification and formal equivalence checking solutions. Overall, we considered the 50th DAC to be a great success. From what we heard, we weren’t alone in our assessment. The exhibit floor was busy all three days and the technical sessions hopping. In general, most of the exhibitors were happy with attendance and thought DAC was worthwhile. No one knew what to expect, given the Austin location and the general health of the economy and EDA industry.

We’re pleased with the number of leads we collected from DAC and attribute much of it to our pre-DAC marketing and public relations campaign. We started upping our visibility around November last year and went into high gear at DVCon earlier this year. I highly recommend this strategy to all DAC exhibitors for next year.
