Today, Jasper announced their new Jasper-Gold Low Power Verification App. This is focused on verifying low power designs with multiple power domains, voltage islands, power shutoff, clock shutoff, and all the other techniques used for reducing power. Of course power is the main driver of SoC design these days, whether it is for… Read More

Calypto, in Three Part Harmony
As Julius Caesar said, “Gallia est omnis divisa in partes tres.” All Gaul is divided into 3 parts. Calypto is similar with three product lines that work together to provide a system level approach to SoC design. Two of those product lines are not unique, in the sense that similar capabilities are available from a handful… Read More
Properly Handing Of Clock Tree Synthesis Specifications
Given today’s design requirements with respect to low power, there is increasing focus on the contribution to total power made by a design’s clock trees. The design decisions made by the front-end team to achieve high performance without wasting power must be conveyed to back-end team. This hand-off must be accurate… Read More
Best Practice for RTL Power Design for Mobile
Mobile devices are taking over the world. If you want lots of graphs and data then look at Mary Meeker’s presentation that I blogged about earlier this week. The graph on the right is just one datapoint, showing that mobile access to the internet is probably up to about 15% now from a standing start 5 years ago.
Of course, one obvious… Read More
GlobalFoundries in Singapore
I hosted a webinar today for GlobalFoundries. Yes, I know that today was TSMC’s Technology Symposium, we weren’t that smart when we picked the date. It was basically a “fireside chat” with me as the moderator asking the questions and Paul Colestock and Aabid Husain as my guests. We actually did it at Cadence… Read More
RTL Power Optimization
More so than most aspects of design, power reduction suffers from a paradox that early in the design cycle when the gains are the largest, the accuracy of power estimation is the lowest, and then late in the design cycle, when everything is known pretty much exactly it is too late to make anything other than trivial optimizations. … Read More
GF, Analog and Singapore
The world is analog and despite enormous SoCs in the most leading-edge process node being the most glamorous segment of the semiconductor industry, it turns out that one of the fastest growing segments is actually analog and power chips in older process technologies. Overall, according to Semico, analog and power ICs, including… Read More
Formal Verification of Power Intent
I can’t imagine that any SoC today is designed without taking intense interest in how much power the chip will consume, whether it is destined for a mobile phone or tethered in a cloud datacenter. One challenge with power is that adding features like voltage islands or power-down areas require changes to the netlist such as… Read More
Sanjiv Kaul: Is HLS About to Take Off?
At the end of last week I talked to Sanjiv Kaul, the new CEO of Calypto. Just to give a little background for those that haven’t been following along at home, Calypto was founded to try and solve the very hard problem of sequential logical equivalence checking (mostly by people from the engineering team that I managed at Ambit).… Read More
High and Low: High Level Synthesis and Low Power
It is so widely accepted that it is already a cliche to say that “power is the new timing.” With more and more chips, the major challenge is not so much to meet timing but to meet timing without blowing out the power budget. Otherwise, you could just crank up the clock rate.
I’m going to be lazy so you can insert your … Read More
