@Tim Edwards @Mitch Bailey Excuse me, I was trying to pass LVS of one of a standard cells such as simple inv_2
on my machine. However, I found this mismatch report. can you suggest me to fix it, please? By the way, i used

netgen -batch lvs "inv_2_scm.spice inv_2_scm" "inv_2_sc.spice inv_2_sc" /home/ahmedreda/PDK/sky130A/libs.tech/netgen/sky130A_setup.tcl

inv_2_sc.spice comp.out

@Ahmed Reda you need to include the standard cell spice.

You probably don’t have well/substrate contacts in the layout either.

Copy code

netgen -batch
read spice $::env(PDK_ROOT)/$::env($PDK)/libs.ref/sky130_fd_sc_hd/spice/sky130_fd_sc_hd.spice 1
lvs "inv_2_scm.spice inv_2_scm" "inv_2_sc.spice inv_2_sc" $::env(PDK_ROOT)/$::env($PDK)/libs.tech/netgen/$::env($PDK)_setup.tcl

That’s just a quick guess. I haven’t tested. You’ll still get the substrate/well mismatches.
