Ever heard of Chip Design Pentagon?
Know what Pentagon is? It is a plane figure which has 5-straight sides and 5-angles. For a perfect pentagon, it needs all its sides and angles to be the same, till the last decimal. Do you know what is the similarity between pentagon and our upcoming workshop “Advanced Physical Design workshop using OpenLANE/SKY130”? Look above image and you would guess it right. It is a perfect blend of topics where even a fresher can jump-start his/her career in chip design in just 5-days
How about benchmarking Opensource openSTA against ——?
So, I took up two STA tools, OpenSTA from openroad project and “——-” from “——-“, to explain, to some extent, what “bench-marking” means to me. I would also encourage everyone reading this blog to come up with their definitions of “bench-marks” for other tools and we can model that. You can fill-up “——” with one of your favorite industry grade EDA tools. The concept of benchmark won’t change
What is set_multi_cpu_usage in physical design or STA?
Do you want to find your answers too? Enroll in the upcoming webinar on “Distributed timing analysis” with Tsung-Wei, do labs on your own, understand the framework and I can guarantee you would be a better STA engineer or Lead than you were before 26th May.
Distributed timing analysis webinar
There are multiple places, we can introduce distributed computing to timing and major motivation is to speed up the timing closure. We have to analyze timing under different range of conditions, typically quantified as modes (test mode, functional mode) and corner (PVT). The number of combinations (timing views) you have to run is typically increasing exponentially with lower nodes. That’s where you need to need to distribute timing analysis across different machines.
The beauty of slack-based timing ECO
A timing ECO should be power, performance and area aware and that was the crux of this webinar, where we discussed several strategies about how to do effective ECO as an expert .Slack based ECO is a beautiful strategy which helps you to achieve your timing target, while helping you to reduce on power and area
