DACis just 33 days away and who wouldn’t want a cool GoPro camerato play with? Your manager will certainly want you to first check out what’s new at DAC if your job involves getting to RTL signoff on time and within budget. The creative folks at Atrenta have figured out how to attract us with the offer of winning a GoPro camera,… Read More

Expert Constraint Management Leads to Productivity & Faster Convergence
The SoC designs of today are much more complex than ever in terms of number of clocks, IPs, levels of hierarchies, several modes of operations, different types of validations and checks for growing number of constraints at various stages in the design flow. As a semiconductor design evolves through several stages from RTL to layout,… Read More
Synchronizer Reliability Metrics
As an example of the need for real-world reliability metrics, consider a modern automobile. We can already buy a car with parking assistance, collision avoidance, autonomous braking and adaptive cruise control features. These new features depend on video image processing that requires high-performance SoC components where… Read More
A Tool Conceived With Designers’ Input and Developed from Scratch
If we look at the past, most of the EDA tools in the semiconductor design space have originated from a designers’ need to do things faster. Regardless of whether it is design exploration, manual design, simulation, verification, optimization (Power Performance Area – PPA) and many other steps in the overall design flow.… Read More
Smart Clock Gating for Meaningful Power Saving
Since power has acquired a prime spot in SoCs catering to smart electronics performing multiple jobs at highest speed; the semiconductor design community is hard pressed to find various avenues to reduce power consumption without affecting functionality and performance. And most of the chips are driven by multiple clocks that… Read More
Hierarchical Clock Domain Crossing
One of the first blogs I wrote on SemiWiki was on clock domain crossing (CDC). I thought it was rather a specialized subject, a sort of minority interest. It turned out to be one of the most-read blogs I’ve written. Modern SoCs have lots of unrelated clocks, maybe hundreds, and so ensuring that signals going from one clock domain… Read More
Clock Domain Crossing, a potted history
Yesterday I talked to Shaker Sarwary, the senior product director for Atrenta’s clock-domain crossing (CDC) product SpyGlass-CDC. I asked him how it came about. The product was originally started nearly 8 years ago, around the time Atrenta itself got going. Shaker got involved about 5 years ago.
Originally this was a small… Read More
