The sky130A.lydrc in open_pdks cannot be used in batch mode for klayout when I use the following command:

klayout -b -rd input=my_layout.gds -rd report=sky130_drc.txt -r drc_sky130.drc

The drc_sky130.drc is renamed from sky130A.lydrc. It reports a series syntax errors due to the header of the XML, So I commented them out, and there are other syntax error derived from XML, such as

&

symbol. Should I just replace those symbol with plain text symbol

&

or there is other dedicated file for running klayout in batch mode? @Tim Edwards

From

mpw_precheck/checks/drc_checks/klayout/klayout_gds_drc_check.py

looks like it's using

mpw_precheck/checks/tech-files/sky130A_mr.drc

for drc.

Thanks for the notes! @Mitch Bailey
