2nd mile-stone in field open-source (efabless open-lane EDA + Google/Sky130 open-process). GitHub is indeed the new RESUME for VLSI industry. Again, let's take a backseat and appreciate/encourage all freshers like
@User to do a similar kind of work, by congratulating them
@User 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.
All of above using open-source RISC-V design (picorv32a) + open-source EDA tools (open-lane by efabless) + open-process (google+skywater130nm).
Here's detailed masterpiece of his work. Its open for review/critics/feedback/comments/usage and everything. Thanks again
