Foundry IP’s vs Macros – 10years to solve this query

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.

7th mile-stone in open-source analog IP design – 10-bit DAC

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.

6th mile-stone in field of open-source – FREE VLSI tool installation course

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

2nd mile-stone in field open-source (open-lane EDA + Google/Sky130)

@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.
