Publish GDS layer map #91

Open Laksen opened 4 years ago

Laksen commented 4 years ago

Currently there doesn't seem to be any way to find the GDS layer id for a given layer.

RTimothyEdwards commented 4 years ago

@Laksen : This document: https://docs.google.com/spreadsheets/d/176OcP2h_TT_pDP2-zBLijlgFUP38LVgMQPlDtpLcrsk/edit?ts=5eff8387#gid=459375686 doesn't tell you what you want to know?

smunaut commented 4 years ago

Also see https://github.com/google/skywater-pdk/pull/89 that aims to merge that document inside this repo.

Laksen commented 4 years ago

@RTimothyEdwards yes, thank you, that contains the relevant information. And with the PR @smunaut linked it should be easy to generate a layer map from it

Adding the resistance and capacitance values in https://github.com/google/skywater-pdk/pull/106

RTimothyEdwards commented 4 years ago

@mithro : Is there anything that actually needs to be done here for this issue?

20Mhz commented 4 years ago

maybe ASCII map files?

rovinski commented 4 years ago

@20Mhz there isn't really a standard for ASCII map files, and every tool seems to have a different format for them.

89 added a CSV file version of the Google doc. IMO if there are any other versions of a GDS layer map, they should be extracted from that CSV via script to maintain a singular layer map source file.
