Consider creating demos / tutorials with Google's new open source PDK? #27

Open mithro opened 4 years ago

mithro commented 4 years ago

I don't know if you heard, but @Google has released a manufacturable PDK for a 130nm process under an open source license. You can find it at https://github.com/google/skywater-pdk and see a talk from me on the topic at https://www.youtube.com/watch?v=EczW2IWdnOM -- the docs are slowly getting published at https://skywater-pdk.readthedocs.io/ and there is a public slack channel you can access via https://join.slack.com/t/skywater-pdk/shared_invite/zt-fkl21w8j-qzxBK852XGR8EFMbRakTMw

With a PDK that can now be downloaded with just a git clone (no NDA or other restrictions), do you think it would make sense to create demos and/or tutorials using this PDK so that people can try out DREAMPlace and also reproduce your results?

@mithro that seems good option I was looking for projects along the newly released PDK too.

Thanks for the suggestion. We are searching around for any open-source designs (in DEF format) generated by the skywater PDK so that we can create a demo. OpenRoad is considering to support the new PDK. We may need to wait a little more time for the toolchain ready with the capability of making new benchmarks.

Please do mention me when you have found out. We can collaborate on making basic demos and brainstorm for novel chip making ideas @limbo018

@msaligane might already have some.

@limbo018 I can help with that. I generated a small testcase using openroad flow. I have a DEF already of a gcd design but I am sure I can generate other DEFs for you. Please let me know what you need exactly.

@msaligane That's great! It would be good if you can generate designs with sizes around 10K - 1M and share the LEF/DEF files for placement.
