I'm trying to get LVS up and running for the first time, but I'm having some difficulty.
I'm using the LVS rule deck from here: https://github.com/laurentc2/FreePDK45_for_KLayout/tree/cb22893f1bf15cabcfe156182a055b4882874f99
The LVS deck is at
lvs/lvs_freepdk45.lylvs. The unit test source GDS is at
INV/INV.gds, and the reference schematic is at
INV/INV.cir. I am running on the cell
When I run the script, I get a mismatch:
It looks like all the pins are matching, but the transistors are not. I'm having trouble understanding why. Is it because the terminal names are in a different case ("gnd" vs. GND)? If so, where is "GND" coming from? "gnd" appears lowercase in both the reference schematic and the source GDS labels.
