Modern SoC designs can use billions of transistors where transistors are grouped into gates, then gates grouped into cells, then cells grouped into blocks, blocks grouped into modules, and so on, creating a complex hierarchy. What a front-end designer conceives of logically for a hierarchy will differ from how an optimized physical… Read More

Requirements Management and IP Management Working Together
I first heard about requirements management back in 1995 while marketing a graphic HDL entry tool for an EDA vendor, and it sounded like a very useful automation approach, however our team quickly discovered that there were too many different vendors for requirements management, so there could be no simple way to integrate with… Read More
Power-Aware Debug to Find Low-Power Simulation Bugs
When I worked at Intel designing custom chips my management would often ask me, “Will first silicon work?” My typical response was, “Yes, but only for the functions that we could afford to simulate before tape-out.” This snarky response would always cause a look of alarm, quickly followed by a second … Read More
Five Things To See at DVCon India 2016
DVCon is an annual Design and Verification Conference that started out in Silicon Valley, then expanded by adding India as a new location. Our semiconductor design and verification world is global in stature, so if you’re living in the region then consider registering for this event held Thursday and Friday, September … Read More
Three Steps for Custom IC Design Migration and Optimization
Popular companies designing smart phones, CPUs, GPUs and Memory components all employ teams of custom IC designers to create the highest performance chips that are as small as possible, and at the lowest costs. How do they go about doing custom IC design migration and optimization when moving from one process node to another one?… Read More
Low Frequency Noise Challenges IC Designs
AMS and RF IC designers have known for years that their circuits are sensitive to noise, because if you amplify noise on an input source to an amplifier circuit then your chip can start to produce wrong answers. Even digital SoC designers need to start taking notice because every SoC is filled with SRAM IP blocks, and at each shrinking… Read More
Did My FPGA Just Fail?
Designing DRAMs at Intel back in the 1970s I first learned about Soft Errors and the curious effect of higher failure rates of DRAM chips in Denver, Colorado with a higher altitude than Aloha, OR. With the rapid growth of FPGA-based designs in 2016, we are still asking the same questions about the reliability of our chips used for safety-critical… Read More
Are Your Transistor Models Good Enough?
SoC designers can now capture their design ideas with high-level languages like C and SystemC, then synthesize those abstractions down into RTL code or gates, however in the end the physical IC is implemented using cell libraries made up of transistors. Circuit designers use simulation tools like SPICE on these transistor-level… Read More
Catching low-power simulation bugs earlier and faster
I’ve owned and used many generations of cell phones, starting back in the 1980’s with the Motorola DynaTAC phone and the biggest usability factor has always been the battery life, just how many hours of standby time will this phone provide and how many minutes of actual talk time before the battery needs to be recharged… Read More
A Software Company Making Hardware
I’ve been a daily Facebook user for many years now and it keeps me in touch with family, friends, some business contacts and even a handful of high-tech companies. My first impression is that Facebook is a very successful, cloud-based, social platform staffed with software developers and a few marketing mavens. On closer… Read More
