@User I'm struggling with an LVS issue with the PNP devices. Netgen correctly reduces 8 parallel PNPs to 1 when no setup tcl is specified. But when the
sky130A_setup.tcl
setup is included it doesn't reduce the PNPs, resulting in 8 individual devices plus many extra nodes. I'm using the PNP gds included with the PDK. The extracted netlist ('drc_cell_lvs.spice') and reference netlist ('bandgap_core_bipolars.spice) are attached. The command I'm using is
netgen -batch lvs drc_cell_lvs.spice bandgap_core_bipolars bandgap_core_bipolar.spice bandgap_core_bipolars sky130A/libs.tech/netgen/sky130A_setup.tcl
I've tried debugging it but hit a brickwall. If you could take a quick look that would be greatly appreciated.
