I simulated this simple circuit yesterday with no problems. To day I made
some minor changes and tried to simulate and I'm getting errors where gnucap
can't recognize netnames that are there. I changed everything back to
yesterdays setup, except for the fedora update I did after booting up, and
I'm still getting these errors. I changed the netname to node 2 and it is
faulting still.
I can't see what I'm doing wrong. I'm listing the output from the netlister
followed by the gnucap attempt and the netlist with the simulation commands:
