Everyone knows that verification is hard and is consuming an increasing percentage of verification time and effort. And everyone should know that system-level verification (SoC plus at least some software and maybe models for other components on a board) is even harder—which is why you see hand-wringing over how incompletely… Read More
Verification complexity and volume has always been on the rise, taking significant amount of time, human, and compute resources. There are multiple techniques such as simulation, emulation, FPGA prototyping, formal verification, post-silicon testing, and so on which gain prominence in different situations and at different… Read More
With growing complexities and sizes of SoCs, verification has become a key challenge for design closure. There isn’t a single methodology that can provide complete verification closure for an SoC. Moreover creation of verification environment including hardware, software, testbench and testcases requires significant … Read More
In today’s world where every device functions intelligently, it automatically becomes active on any kind of stimulus. The problem with such intelligence is that it can function unfavorably on any kind of bad stimulus. As the devices are complex enough in the form of SoCs (which at advanced process nodes are more susceptible to … Read More
Once upon a time there was a struggle for verification completion of semiconductor designs at gate level. Today, beyond imagination, there is a struggle to verify a design with billions of gates at the RTL level which may never complete. The designs are large SoCs with complex architectures and several constraints of area, performance,… Read More
While focus of the semiconductor industry has shifted to DACin this week and unfortunately I couldn’t attend due to some of my management exams, in my spare time I was browsing through some of the webpages of Cadenceto check their new offerings (although they have a great list of items to showcase at DAC) and to my pleasure I came across… Read More
In the current semiconductor design landscape, the design size and complexity of SoCs has grown to large extent with stable tools and technologies that can take care of integrating several IPs together. With that mammoth growth in designs, verification flows are evolving continuously to tackle the verification challenges … Read More
Big SoC designs typically break existing EDA tools and old methodologies, which then give rise to new EDA tools and methodologies out of necessity. Such is the case with the daunting task of verification planning and management where terabytes of data have simply swamped older EDA tools, making them unpleasant and ineffective… Read More
In the current decade of SoCs, semiconductor design size and complexity has grown by unprecedented scale in terms of gate density, number of IPs, memory blocks, analog and digital content and so on; and yet expected to increase further by many folds. Given that level of design, it’s imperative that SoC verification challenge has… Read More
At this year’s DAC, I spoke with several friends at Cadence. I got the distinct impression that something at Cadence had changed. There was a sense of pride and accomplishment that it seems to me had drifted away over the years. Now employees were speaking with true conviction about the accomplishments of the product development… Read More
