Hi Adam, Thanks for the pointers. I will try them out. I am considering using it for a class I am teaching this summer. Also, I will be happy to help developing it further. What is its current state? what is missing?
Btw, are you on skywaterr-pdk Slack space? If not, you may join @ https://invite.skywater.tools. I think your contributions to the #electric channel will be great. I am sorry that you did not make use of the Open MPW program. Btw, I helped designing the harness chip (Caravel) being used for this program. Also, I am the architect of OpenLane, the open source digital ASIC flow. I will be more than happy to help you to submit designs to future shuttles. Finally, have you seen this: https://www.efabless.com/chipignite/2106Q? I think this is what you are looking for. A commercial MPW for SKY130A. The MPW slot costs less than 10K USD (100 QFN or 300 WCSP parts) with the option to use the full die area the way you want. I recommend that you get in touch with mkk at efabless.com Thanks. --mshalan On Friday, June 11, 2021 at 9:10:54 PM UTC+2 Adam Joseph wrote: > On Wed, 9 Jun 2021 21:36:03 -0700 (PDT) > "'shalan' via Electric VLSI Editor" <electr...@googlegroups.com> > wrote: > > Also, what is the current status of Sky130A PDK support. > > Hello, Shalan, > > My company, Western Semiconductor, wrote the initial sk130 PDK for > Electric which is still available and you are welcome to use it: > > https://gitlab.com/westernsemico/com.westernsemico.vlsi > > We did this before Skywater announced the very unusual tape-in > requirements for Google-subsidized runs, especially the requirement > that subsidized runs be wrapped with the Skywater Management Engine. > > After those requirements were released, I realized that targeting the > Google-subsidized runs is not a good use of engineering resources.
