Also, I think these coils are just very rough test because I can't even find a spice model in the entire pdkmanili

Failure to read entire subtree of cell.
Is there something wrong with the way I am loading the magic file? I use the command "magic example_por.mag" and have this when I load into magic
Thanks!Arman Avetisyan

This extracted netlist does not match the original netlist (comparison done with netgen) because in the original netlist, all the fet bodies are connected to GND. Let me know if you have any tips to resolve this.
Below is a picture of my cell, in case you can notice something obviously wrong!Derek Hines-Mohrman

feature well supported for sky130?
I am trying to test it out, but it always causes a seg fault.Yueting Li

on Magic it finds one unintentional capacitor. I can not understand how does it extract such cap because it has no PDK-specific type with it. Here’s is my extracted netlist:
* SPICE3 file created from INV.ext - technology: sky130A
.subckt INV OUT IN VDD GND
X0 OUT IN VDD VDD sky130_fd_pr__pfet_01v8 ad=0p pd=0u as=0p ps=0u w=840000u l=150000u
X1 OUT IN GND GND sky130_fd_pr__nfet_01v8 ad=0p pd=0u as=0p ps=0u w=420000u l=150000u
C0 VDD GND 2.26fF
.ends
As you can see it’s a very simple inverter, also I’ll put my layout in the attachments.
1. Is there anything wrong with my layout which leads to such cap?
2. Is it going to produce an LVS error if my goal is the following inverter?
.subckt INV OUT IN VDD GND
X0 OUT IN VDD VDD sky130_fd_pr__pfet_01v8 ad=0p pd=0u as=0p ps=0u w=840000u l=150000u
X1 OUT IN GND GND sky130_fd_pr__nfet_01v8 ad=0p pd=0u as=0p ps=0u w=420000u l=150000u
.ends
