Power analysis has materialized as a principal theme in today’s world in semiconductor industries. As very large scale integrated circuit (VLSI) are far beyond from human ability because of complexity in nature. So to analyse power in these circuits we use open source computer aided tools, plenty of tools are available but most of them are costly. I designed an open source power analysis tool for the academic use. This tool gives out values of average and leakage power of any circuit by just giving the netlist of circuit file along with name of supply voltage as input. This tool is designed in python language.
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
A great one – not only for VSD, but also for entire VSD community. The journey has just begun, in nutshell, below image shows a well-designed VLSI Skilling model (VSD Workshops + VSD-IP design Internship + Tapeout[working on it]), which is not just participants driven but also silicon proven. To summarize, given a problem statement, VSD Interns and participants, who have gone through this rigorous training and designing model will have much better ways to figure out solutions by themselves.
Ashutosh had joined our VSD Research IP design internship group 8-weeks back, along with 30 other interns. His journey on was from “I can’t, its too difficult” to “I did it”. Personally, only I know how hard it was for him when he saw an industry grade 10-bit DAC specifications on VSD IP website. We managed to achieve post-layout DNL of 3.5LSB and INL of 3.7LSB, which as per experience, is really tough for a fresher to achieve in a span of 8-weeks, but not impossible.
A full-fledged video lectures on step-by-step process to install OpenLANE EDA tool chain and Sky130 PDK open-process on your own laptop, from scratch. There is a dependency on vsdflow, though for fresh users and with Windows or fresh Unix machines. To do something like this, it needs a clear focus on end vision, with very good VLSI fundamentals, which demands hours of efforts every day
This time its @Reuel did a pretty great job of building a pretty compact 6T-SRAM cell and he is just a third year engineering student
We had Makerchip IDE, TL-Verilog, Day wise Slack channels, Classroom GitHub and VSD-IAT – All of them so seamlessly integrated that every participant followed the loop and there you go. Out of 110 participants, 35 participants built entire basic RISC-V CPU core which is close to 30% participants, and all in 5-days
@Yash joined our research project group under VSD Research internship program which runs for 8-weeks. He was supposed to explore openRAM memory compiler flow, develop all custom cells required by openRAM using OSU180nm and generate 4kB SRAM with an access time of 2.5ns
@Nickson joined our research project group under VSD Research internship program which runs for 8-weeks. He was supposed to develop flow for standard cell design and characterization using all open-source tools – magic/ngspice, then plug those standard cells into open-source PNR flow by open-lane, and benchmark RTL2GDS flow results. This needed a knowledge, not only of PNR, but device physics, custom layout, DRC/LVS and then (finally) Physical design/STA.
