This might be related to this issue, to be further investigated: https://github.com/KLayout/klayout/issues/1279
I tiried to workaround by:
copy /headless/.klayout/tech/sky130
in 2022.12
paste /headless/.klayout/tech/sky130
in latest
The warning is gone but magic still can't display the modified gds file.
In 2022.12
the folder /headless/.klayout/tech/sky130
with sky130.lyp
exists, but in latest
it does not. I suspect there's information about the sky130
path embedded in the openLane-generated gds file (see file - layout properties
and tools - manage technologies
), therefore klayout still searches for sky130.lyp
despite the command line option
I think I have found the issue, will try a patch of the klayout techfiles.
Closed, for explanation see here https://github.com/RTimothyEdwards/magic/issues/221
Describe the bug GDS files can not be viewed with magic if they were edited with klayout
