Is your setup file correct? 
.../netgen/sky130A_setup.tcl
Check your netgen output for error messages (ie. can't find file, etc.) Also, I recommend putting the layout netlist first and the schematic netlist second. From the setup file.
Copy code
# NOTE:  In accordance with the LVS manager GUI, the schematic is
# always circuit2, so some items like property "par1" only need to
# be specified for circuit2.

Oh man. You are exactly right. I had accidentally broken the path to the config file (in the last message I had just truncated the path to keep the message clear). Oddly, however, I don’t see any error messages about no config file or a bad path. I have also swapped the layout and schematic netlists. Thank you so much for your help! I’m sorry it was such a stupid mistake.

The error messages don't appear in the log file but you should be able to see them in the stdout.

LVS Done.
Hmmm….Is there debugging flags or envs?
m
This is the output from a correct setup, I believe. Compare it to the output with a bad setup file.
m
Huh. That’s the old output without a setup file
Oh, I found a line now: with a setup file there is a line that says, 
Reading setup file ./netgen/sky130A_setup.tcl
So I must look for that line in the future. Thanks a lot!
