Is there a layer map file?

[growly]

I need a straightforward mapping of layer names to GDS types/subtypes. I believe this information is captured by various tool configuration files, like gf180mcu.lyp for klayout, but it would be helpful to have the source in order to produce another tool-specific configuration file instead.

For sky130 such a file was available in non-public versions, so I'm curious if there's a similar situation for this PDK.

I think I could parse the magic gf180mcuA-GDS.tech for this too, but it also isn't straightforward.

There was also the SKY130 (SkyWater PDK) -- Layer (GDS-II / Magic / Calibre / etc) Information spreadsheet for SKY130.

@atorkmabrains - @growly mentioned he had found the gf180mcu.lyp file but was looking for something a bit easier to process.

Yes I was hoping for a simpler format, such as the source of whatever produced the .lyp in the first place (a spreadsheet would be nice). However I could extract it from the gf180mcu.lyp file or the magic file, if someone could please clarify what this means?

1. <source>1/222@1</source>
2. <source>Poly2 30/0@1</source>

Example (1) doesn't have a layer name?

The numbers are layer/datatype@something? What is the last number?

@growly I'm sorry misread what you need. Here is a CSV file that is used for documentation. You could use pandas to read this file in Python for example:

Great, thank you!
