An Open ISA, a Closed Mindset — Predictive Execution Charts a New Path
The RISC-V revolution was never just about open instruction sets. It was a rare opportunity to break free from the legacy assumptions embedded in every generation of CPU design. For decades, architectural decisions have been constrained by proprietary patents,… Read More
It was back in 1991 that Cadence first announced the Virtuoso product name, and here we are 32 years later and the product is alive and doing quite well. Steven Lewis from Cadence gave me an update on something new that they call Virtuoso Studio, and it’s all about custom IC design for the real world. In those 32 years we’ve… Read More
Having the right tool for the job at hand is always a joy, and when your IC project involves RTL code, gates, transistors and even parasitic interconnect, then you need some EDA tool help for debugging and finding out why your design behaves the way it is. An FAE named Sujit Roy did a conference call with me last week to show what StarVision… Read More
You’ve heard about Meltdown and Spectre and you know they’re really bad security bugs (in different ways). If you’ve dug deeper, you know that these problems are related to the speculative execution common in modern processors, and if you dug deeper still you may have learned that underlying both problems are exploits called timing… Read More
I first met Jason Oberg, CEO and one of the co-founders of Tortuga Logic, several years ago when I was still at Atrenta. At that time Jason and Jonny Valamehr (also a co-founder and the COO) were looking for partners. The timing wasn’t right, but we’ve stayed in touch, for my part because their area of focus (security) is hot and likely… Read More
DC converter circuit efficiency can have a big effect on the battery life of mobile devices. It also can affect power efficiency for wall-power operated circuits. Even before parasitics are factored in, converter circuit designers have a lot of issues to contend with. Optimizing circuit operation is essential for giving consumers… 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
My IC design career started out with DRAM design, characterization and verification back in the 1970’s, so I vividly recall how much SPICE circuit simulation was involved, and how little automation we had back in the day, so we tended to cobble together our own scripts to help automate the process a bit. With each new process… Read More
Every year at DAC I enjoy making the rounds to see what’s new with SPICE circuit simulators, so on June 3rd I met with Xiuya Liand Dan Zhuof Cadence in San Francisco to get an update about their Spectre tool. There’s plenty of competition in the SPICE area from Mentor Graphics (Analog FastSPICE, Eldo, ADiT), Synopsys … Read More
I’m keenly interested in SPICE circuit simulators, so at DACI met with John Piercefrom Cadence to get an update on what’s new this year.
