Cache Coherence Everywhere may be Easier Than you Think

Cache Coherence Everywhere may be Easier Than you Think

Heterogenous cache coherence min

I attended one of the Arm partner events in Cambridge many years ago, when they first talked about the coherent hub for managing cache coherence. I was impressed, but the obvious question even then was how any non-Arm IP was going to hook into this hub. They had a solution, of course, the ACE interface, and I left satisfied. As is the … Read More

CEO interview

You may remember Andreas from his time at Synopsys, where he led the new Software Integrity Business Unit. He joined Tortuga Logic a couple of months ago to lead the company. Given his background in software security, I was eager to get a CEO interview. Andreas is a EE with background at IBM in the PowerPC and EDA. He directed Cadence… Read More


Low Energy Intelligence at the Extreme Edge

Low Energy Intelligence at the Extreme Edge

Low Energy Intelligence

Intelligence at the edge is a hot topic these days. Not having to go all the way to the cloud to recognize objects, faces, speech and so on. But I find promoters can be rather fuzzy about what they mean by “the edge”. For many, intelligence at the edge means intelligence closer to the edge than the cloud. In a gateway for example. Not actually… Read More

Israel and Automotive Safety. More Active Than You May Think.

autonomy min

CadenceLIVE ran a session recently in Europe which I thought would be interesting to check out, especially around automotive needs. The live sessions were too early/late for me (middle of the night) and sadly the talks I really wanted to hear weren’t recorded. Instead, I dug around for updates on automotive electronics in Europe.… Read More


Covering Configurable Systems. Innovation in Verification

Covering Configurable Systems. Innovation in Verification

Covering configurable systems is a challenge. What’s a good strategy to pick a small subset of settings and still get high confidence in coverage? Paul Cunningham (GM, Verification at Cadence), Jim Hogan and I continue our series on research ideas, here an idea from software testing which should also apply to hardware. Feel free… Read More

scan chains crossing power domainspng

In the early days of Atrenta I met with Ralph Marlett, a distinguished test expert with many years of experience at Zuken and Recal Redac. He talked me into believing we could do meaningful static analysis for DFT-friendliness at RTL. His work with us really opened my eyes to the challenges that test groups face in integrating their… Read More


Randomization Fools Us Some of the Time

Randomization Fools Us Some of the Time
by Bernard Murphy on 10-13-2020 at 6:00 am

random min

Though hopefully not some of us all of the time. Randomization is a technique used in verification to improve coverage in testing. You develop tests you know you have to run, then you throw randomization on top of that to search around those starter tests, to explore possibilities you haven’t considered. Truly random tests are not… Read More

Arm Pushes Mobility, Industry

Again on the theme of rationalizing NVIDIA’s $40B acquisition of Arm, two more hot areas for growth are mobility and industrial automation markets. NVIDIA is already strong in intelligent mobility and Arm is is virtually everywhere in the modern car. Ditto for robotics in industry. In fact the two domains have significant overlap:… Read More

Arm Neoverse

I’ve covered Arm Neoverse updates a few times already, a span of products with application from the cloud through infrastructure to the edge. Logical strategy of course but Arm has been delivering some impressive wins suggesting this is more than just a loose marketing concept. Overlap with NVIDIA in datacenters and supercomputing… Read More

I wasn’t familiar with Veriest, I’m guessing you may not be either. They are a design and verification services company based in the Tel Aviv area (Israel). The CEO, Moshe Zalcberg, was earlier GM for Cadence in Israel. Echoes for me of the early days working with Ajoy Bose in Interra. Veriest have a big emphasis in verification, for… Read More
