As digital transmission speeds increase, designers use various techniques to improve the signal-to-noise ratio at the receiver output. One such technique is the Decision Feedback Equalizer (DFE) scheme, commonly used in high-speed Serializer-Deserializer (SerDes) circuits to mitigate the effects of channel noise and … Read More
We all know signal integrity and power integrity are becoming more important for advanced design. Like package engineering, the obscure and highly technical art of SI/PI optimization has taken center stage in the design process. And the folks who command expertise in these areas have become the rock stars of the design team. I … Read More
In early April, Gabriele Saucier kicked off Design & Reuse’s IPSoC Silicon Valley 2021 Conference. IPSoC conference as the name suggests is dedicated to semiconductor intellectual property (IP) and IP-based electronic systems. There were a number of excellent presentations at the conference. The presentations had been… Read More
ASICs by definition are designed to meet the respective applications’ requirements. ASIC engineers deploy various design techniques to maximize performance, minimize power and reduce chip size. But is there more that can be done after the GDSII is taped out? A recent press release from Alchip Technology dated Feb 4, 2021 claims… Read More
Work from home (WFH) has become a normal occurrence this past year. “Do you work from home?” “Of course, where else?” Samtec is taking the whole work from home thing up a notch with a new webinar lineup for 2021. Back by popular demand, they are launching a new series of educational webinars. Started last year, the gEEk SpEEk Webinar… Read More
At the recent DesignCon 2020 in Santa Clara, Cadence introduced a new product, Sigrity Aurora. You won’t find a press release about this announcement. Rather, Brad Griffin, product management group director at Cadence, presented Sigrity Aurora in the theater at the Cadence booth. This one caught my eye and deserves some discussion.… Read More
High-speed design requires addressing signal integrity (SI) and power integrity (PI) challenges. Power integrity has a frequency component. The Power Distribution Network (PDN) in designs has 2 different purposes: providing power to the chip, and acting as a power plane reference for transmission-line like propagating … Read More
While I missed ANSYS (and indeed everyone else) at DAC this year, I was able to attend the ANSYS Innovation Conference last week at the Santa Clara Convention Center. My primary purpose for being there was to listen to a talk by eSilicon which I’ll get to shortly, but before that I sat through a very interesting presentation on the growing… Read More
The engineering team for the design and analysis of a complex system consists of a diverse set of skills — with the increasing emphasis on both high-speed interface design and multi-domain power management, a critical constituent of the team is the group of signal integrity (SI) and power integrity (PI) engineers.
The training… Read More
It’s hard to believe but this is DesignCon #22 and being a Silicon Valley conference I have attended my fair share of them. This year it seems like high speed communications will take the lead followed by the latest on PCB design tools, power and signal integrity, jitter and crosstalk, test and measurement tools, parallel … Read More
