05/13/2022, 11:34 PMI am wondering where this mismatch comes from. Is it due to routing mismatch (like I route a wrong wire in layout and does not match the net in the schematic)?

05/14/2022, 12:42 AMThe command I run netgen is netgen -batch lvs “/home/users/xw5/.xschem/simulations/mux2-1.spice mux2-1” “mux_test.spice mux_test” sky130A_setup.tcl
