Thanks to my growing involvement in formal (at least in writing about it), I was happy to accept an invite to this year’s Oski DVCon dinner / Formal Leadership Summit. In addition to Oski folks and Brian Bailey (an esteemed colleague at another blog site, to steal a Frank Schirrmeister line), a lively group of formal users attended… Read More
Formal methods are a vital complement to other tools in the verification arsenal, but they’re not without challenges. One of the more daunting is the “inconclusive” result – that case where the tool seems to be telling you that it simply gave up trying to figure out if a particular assertion is true or false. Compounding the problem,… Read More
Simulation dominates hardware functional verification today and likely will continue to dominate for the foreseeable future. Meanwhile formal verification, once thought to be a possible challenger for the title, has instead converged on a more effective role as a complement to simulation. Formal excels at finding problems… Read More
Two recently announced vulnerabilities in major processor platforms should remind us that bugs don’t organize themselves to appear only in domains we know how to test comprehensively. Both Meltdown and Spectre (the announced problems) are potential hardware system-level issues allowed by interactions between speculative… Read More
Periodically Mentor does us all a big favor by commissioning a survey of verification engineers across the world to illuminate trends in verification. This is valuable not only to satisfy our intellectual curiosity but also to help convince managers and finance mandarins that our enthusiasm to invest in new methods and tools … Read More
In the early days of IP reuse and platform-based design there was a widely-shared vision of in-house IP development teams churning out libraries of reusable IP, which could then be leveraged in many different SoC applications. This vision was enthusiastically pursued for a while; this is what drove reusability standards and … Read More
Facing rapidly growing challenges in getting to respectable coverage, designers have been turning more and more to formal verification, not just to plug gaps but increasingly to take over verification of significant components of the testplan. Which is great, but at the end of the day any approach to verification must be measured… Read More
It’s not easy having to deliver one of the last tutorials on the last day of a conference. Synopsys drew that short straw for their tutorial on formal methodologies at DVCon this year. Despite that they delivered an impressive performance, keeping the attention of 60 attendees who said afterwards it was excellent on technical content,… Read More
DVCon is fast approaching, less than 3 weeks away. As a verification geek, this must be one of my favorite conferences, so I’ll be there; you’ll see me at tutorials, presentations and wandering around the Exhibit hall. (Pictures here from the 2016 DVCon – many of the same attendees will be at this year’s conference after all :cool:)… Read More
Formal verification for hardware was stuck for a long time with a reputation of being interesting but difficult to use and consequently limited to niche applications. Jasper worked hard to change this, particularly with their apps for JasperGold and I have been seeing more anecdotal information that mainstream adoption is growing.… Read More
