Error message by klayout as it does not find the `.lyp` file

[hpretl]

Expected Behavior

klayout starts w/o error message.

Actual Behavior

When klayout is started with klayout -e -nn $PDKPATH/libs.tech/klayout/tech/$PDK.lyt -l $PDKPATH/libs.tech/klayout/tech/$PDK.lyp example.gds then the following error message is shown:

Warning: Initialization of layers failed: Unable to open file: /headless/.klayout/tech/sky130/sky130.lyp (errno=2)

When looking into the .lyt file, the following can be seen:

<base-path>$(appdata_path)/tech/sky130</base-path>
 <original-base-path>$(appdata_path)/tech/sky130</original-base-path>
 <layer-properties_file>sky130.lyp</layer-properties_file>

Question:

• Why the reference here to appdata_path? The agreed quasi-standard is to use $PDK_ROOT and $PDK.
• Why the reference to sky130.lyp and not to sky130A.lyp or sky130B.lyp?

@hpretl for the sky130.lyp vs sky130A.lyp error I think this is related to https://github.com/RTimothyEdwards/open_pdks/issues/332#issuecomment-1632079484
