I'm trying to LVS a basic inverter in sky130 using their lylvs scripts. It seems to extract the exact same netlist, but for some reason, nothing matches. How can I go about debbugging this?

The reference netlist:
.subckt sky130_fd_sc_hd__inv_1 A VGND VNB VPB VPWR Y X0 VGND A Y VNB sky130_fd_pr__nfet_01v8 w=650000u l=150000u X1 VPWR A Y VPB sky130_fd_pr__pfet_01v8_hvt w=1e+06u l=150000u .ends
I tried changing device types (X <-> M).
I'm not sure how to attach my lvsdb file to a forum.
