Hi all, does anybody have a KLayout Z Stack for SKY130?
n
Hi, thank you, I had no idea that Klayout could do that. I was using GDS3D to view a 3D render of the gds. I took the techfile that already exists for SKY130 in GDS3D and adapted it for Klayout. Seems consistent with the process stack diagram (https://skywater-pdk.readthedocs.io/en/main/rules/assumptions.html#process-stack-diagram), although I'm not sure about the position of CAPM and CAP2M layers. You might want to check GDS3D too (https://github.com/trilomix/GDS3D)

Awesome, thanks. I tried GDS3D and it had pretty limited features, I wanted to hide layers. The tinytapeout viewer is what I'd ideally use but it's far too slow for proper designs (the gltf file for my design is 250MB, it just froze)
How do you use this? I can't find anything about the lyd25 file format, copying the non-XML part into the z stack text editor resulted in errors
Apparently the released source code for KLayout 0.27.12 doesn't have the lyd25 DSL parser, even though it's been released this month, and the parser is in master since February

Mmm, that's strange, the version I'm using is 0.28, I cloned it from Github on 19/September, but I don't see it
e
Makes sense. I'll build it from the master branch then as well.

@Norman Méndez I can't seem to download this lyd25 file. Is it gone from the history?
n
@Matthew Guthaus I can download it without issues, here is again
m
It just says "Binary" for me and doesn't download
Is it in a repo somewhere?
n
Not one that I'm aware. Try with this one, copy and in Klayout ->Tools ->2.5d view -> New 2.5d script and paste it

@Norman Méndez There were a couple mistakes in the heights. I fixed them here.
