At DVCon today I talked to Sanjiv Kaul, the CEO of Calypto. Just as a reminder, Calypto have 3 products, SLEC (sequential logical equivalence checking, also called sequential formal verification), PowerPro (sequential RTL level power reduction) and Catapult High Level Synthesis (that they took over from Mentor in 2011 in a complicated… Read More

Verification of Power Delivery Networks
Power delivery networks (PDN) are the metal structures on a chip that delivers the power. In a high-end desktop SoC this might be delivering as much as 150W, and with voltages around 1V that means over 150 amps of current. Clearly getting the PDN correct is critical for a correctly functioning chip. One of the challenges to verifying… Read More
Power Control Moving into Hardware
Sonics have been building networks-on-chips (NoCs) for a long time and have amassed a rich patent portfolio. So being granted a new one isn’t usually deemed press-release-worthy. However, their latest patent on power management is pretty significant. It is patent 8,601,288 titled “Intelligent Power Controller”.
Historically… Read More
Grid Vision 2050 – Unified & Open Across The Globe
Whenever there is good momentum in a particular technology, IEEEtakes major initiative to standardize the procedures, formats, methods, measurements etc. involved in the technology to proliferate it for the advantage of wider community. And that becomes successful by active participation and collaboration of both producers… Read More
Untangling snags earlier and reducing area by 10%
The over 20 years of experience behind Synopsys Design Compiler is getting a new look for 2014, and we had a few minutes with Priti Vijayvargiya, director of product marketing for RTL synthesis, to explore what’s in the latest version of the synthesis tool.
Previewed today, Synopsys Design Compiler 2013.12 continues to target … Read More
How to Optimize Analog IPs for High-end SoCs?
Gone are the days when analog design had its sweet space on a single chip. However, it’s the main driver in this new electronic world which is geared by Internet-of-Things, wireless, mobile, remote control and so on. How does an electronic device sense a touch by human, motion, temperature, sound etc.? It’s the analog circuitry … Read More
2013 Awards, and the Winner is…Power
Of all the things that designers have to worry about in the power-performance-area (PPA) equation, the most challenging is power. SoCs have reached a point that we can put a lot of stuff on them, but if we are not careful we cannot light it all up at once. Dark silicon, where we put subsystems on a chip but then don’t have enough … Read More
How to Assure Quality of Power and SI Verification?
As power has become one of the most important criteria in semiconductor design today, I was wondering whether there is a standard set for the power verification for an overall chip. We do have formats evolved like CPF and UPF and there are tools available to check power and signal integrity (SI), however I don’t see a standard objective… Read More
The Leading Edge Depends on What You Are Doing
At Semicon Japan a few days ago, Subi Kengeri of GlobalFoundries delivered the keynote. While he covered a number of topics, using Tokyo’s recent win of the 2020 Olympics as a hook, one major theme was the increasing importance of processes other than the bleeding edge digital processes that get all the news.
What is leading… Read More
Addressing Power at Architectural and RTL Levels
Major power reductions are possible by reducing power at the RTL and system levels, and not just at the gate and physical level. In fact, as is so often the case in design, changes can have much more impact when done at the higher level, even given that at that point in the design there is less accurate feedback about changes. Later the… Read More
