I've had a few cases where students have changed the pin names in the schematic but didn't update the symbol yet. This gives a netlist with the 'old' pin names and causes quite some confusion when LVS still isn't matching. Would it be an option to detect this when generating the netlist and produce a warning?

Here is an example of the command I'm using inside shell script:
! /bin/bash
xschem -n -s -r -x -q --tcl "set lvs_netlist 1" --rcfile $PDK_ROOT/$PDK/libs.tech/xschem/xschemrc -o ../netlist/schematic -N sky130_ef_ip__rdac3v_8bit.spice sky130_ef_ip__rdac3v_8bit.sch
