Power in Test at RTL Defacto Shows the Way

Power in Test at RTL Defacto Shows the Way

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. Central to NVIDIA Strategy?

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

Siemens PAVE360 Stepping Up to Digital Twins

Siemens PAVE360

The idea of a digital twin is simple enough. You use a digital model of a car, aircraft, whatever to test design ideas and prove your design will be robust across a wide range of scenarios before you commit millions of dollars and lives to proving out the real thing. As Siemens have accomplished in their PAVE360 platform. There are a … Read More


Verifying Warm Memory. Virtualizing to manage complexity

Verifying Warm Memory. Virtualizing to manage complexity
by Bernard Murphy on 09-24-2020 at 6:00 am

Verifying warm memory

SSD memory is enjoying a new resurgence in datacenters through NVMe. Not as a replacement for more traditional HDD disk drives, which though slower are still much cheaper. NVMe storage has instead become a storage cache between hot DRAM memory close to processors and the “cold” HDD storage. I commented last year on why this has become… Read More

Based on press coverage and technical paper volume, you could be forgiven for thinking that Korea had decided to take a pass on AI mania, or maybe just to dabble a little here and there to stay abreast of trends. But you’d be wrong. Korea is very active in AI; they don’t feel a need to trumpet what they’re doing from the rooftops. If you … Read More
