#67 PNP LVS Issues
Issue opened by yrrapt
Originated on the open_pdks slack channel:
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
