@mithro @olofk fyi @gregdavill @xobs were you successful to plug SERV to the SRAMs macros present in the GF180MCU PDK https://github.com/google/globalfoundries-pdk-ip-gf180mcu_fd_ip_sram/tree/9c411928870ce15226228fa52ddb6ecc0ea4ffbe

You can view the notebook at https://github.com/chipsalliance/silicon-notebooks/blob/74579085cd72205f3f0b7849aad31257638fa5fa/serv-openlane-gf180mcu.ipynb ?

Title / description of the first cell seems to still be Digital inverter with OpenLane?

[olofk]

Cool! As you mentioned, it would be great to have this running with SRAM instead. I suspect that would make it like ten times smaller :)

Also, would be cool to see if we can run this through FuseSoC for better scalability

https://colab.research.google.com/github/proppy/silicon-notebooks/blob/serv/serv-openlane-gf180mcu.ipynb should give you the current HEAD of the pr branch.

Do you think this should be done in this PR, or should be file an issue about it?

Also, would be cool to see if we can run this through FuseSoC for better scalability

Same question!

We might even want a different notebook? serv-fusesoc-gf180mcu.ipynb.
