Guidance for asap7 or nangate15

[hchenji]

Have been using this repo with mflowgen (works great, thanks). I am trying to add more PDKs, such as ASAP7.

Is there any script/documentation/guidelines that will help generate a full view for other PDKs and stdcells, using the files from the vendor? For e.g., ASAP7's routing tech does not define any resistance/capacitance for the metal layers, which means I cannot generate the Milkyway lib for asap7, so I'm pretty much stuck at the synthesis step in mflowgen. Similarly, antenna and welltap cells seems to be missing. Any help with getting around these problems would be greatly appreciated.
