It was back in July of 2012 that the acquisition of Sigrity by Cadence was announced. Although Cadence is a dominant player in both IC and board layout tools, they did not have an electromagnetic (EM) signal integrity solution in their portfolio. This acquisition marks a turning point for the EM/SI sector – tight integration… Read More

ANSYS Talks About Multi Physics for Thermal Analysis at DesignCon
ANSYS makes a big deal of being a multi-physics company. Still it has taken them a while to fully integrate Apache. Nevertheless it seems like there is a compelling argument for combining technologies to solve SOC design problems. Frankly most chip designers would be hard pressed to think of a reason for using computational fluid… Read More
Silvaco TCAD Webinar
TCAD is a somewhat specialized area since not that many people design semiconductor processes compared to the number who design chips. Bit without TCAD there would be no chips. One area where the two domains intersect is that of SEE, where neutrons (mainly) can cause a flop or a memory bit to change. Since we live on a radioactive planet… Read More
30+ Years of Semiconductors – The base matters!
Although CMOS technology in semiconductors was patented in 1960s, commercial ICs and electronic systems based on CMOS ICs started picking up in 1970s, and the real growth with personal computer (PC) market took place in 1980s. Then Intelmicroprocessors started dominating the semiconductor market with increasing processing… Read More
Measuring Metastability
Measuring metastability is just 50 years old this year. In 1965 my colleague Tom Chaney took a sampling ‘scope picture of an ECL flip-flop going metastable. S. Lubkin had made mention of the phenomenon over a decade before that, but at that time most engineers were unaware of the phenomenon or did not believe it actually existed. … Read More
How Imagination tested the PowerVR Series6XT
We have been hearing for some time about the Synopsys HAPS-70 and how they have co-created the hardware and software architecture for FPGA-based prototyping with their customers. Now, we see details published by Synopsys on how they collaborated with Imagination on the design of the PowerVR Series6XT GPU.
The first thing to come… Read More
Tracing Insight into Advanced Multicore Systems
After knowing about the challenges involved in validating multicore systems and domains of system and application level tracing as explained by Don Dingee in his article “Tracing methods to multicore gladness” which is based on the first part of Mentor Embedded multicore whitepaper series, it’s time to take a deeper insight … Read More
Managing Semiconductor IP
SemiWiki blogger Eric Esteve does an excellent job writing about all of the semiconductor IP available, and the popularity of IP is only growing more each year. Here’s a projection from IBS about semiconductor IP showing revenues of $4.7B by 2020:
Analyst Gary Smith divides IP into three broad categories: Functional, Foundation… Read More
Analyzing Power Nets
One of the big challenges in a modern SoC is doing an accurate analysis of the power nets. Different layers of metal have very different resistance characteristics (since they vary so much in width and height). Even vias can cause problems due to high resistance. Typically power is distributed globally on high-level metal layers,… Read More
Not All RTL Synthesis Approaches are the Same
My first experience with logic synthesis was at Silicon Compilers in the late 1980s using a tool called Genesil. Process technology since that time has moved from 3 um down to 20 nm, so there are new challenges for RTL synthesis. Today you can find logic synthesis tools being offered by the big three in EDA: Synopsys, Cadence, Mentor… Read More
