SKY130 klayout -e not loading PDK layers.

[njcoburn]

This error appears when opening klayout -e
When clicking the SKY130 PDK within klayout, also generates the following error. Layers of .gds are not named appropriately.

@njcoburn

can you try to edit $CONDA_PREFIX/share/pdk/libs.tech/klayout/tech/sky130A.lyt, and replace those three elements:

 <base-path/>
 <original-base-path>$PDK_ROOT/$PDK/libs.tech/klayout</original-base-path>
 <layer-properties_file>sky130A.lyp</layer-properties_file>

[njcoburn]

Copying the sky130A.lyp file from /usr/local/google/home/nigelcoburn/MS_SKY130/silicon-env/share/pdk/sky130A/libs.tech/klayout/tech to /usr/local/google/home/nigelcoburn/.klayout/tech resolved the layer read issue as shown.

I also edited the file sky130A.lyt file [directory: /usr/local/google/home/nigelcoburn/MS_SKY130/silicon-env/share/pdk/sky130A/libs.tech/klayout/tech] line 9 to <layer-properties_file>sky130A.lyp</layer-properties_file>

When running klayout -e I still get the following errors:
