The CPERSQDIST values in the standard cell technology LEF files are all the same (wrong) value.
Even if the google repository fixes the values in the their tech LEF files, the google repository only has the nominal case technology LEF file, leaving open_pdks to generate the min and max corner case files (which is is currently doing, to fix the layer resistance values).
Updating the existing script to generate the min/max corner values for CPERSQDIST is easy enough once the values have been determined (parasitic capacitance tables from which these values can be derived exist in the open PDK repositories).
