I searched this and the RF forum, but couldn't find a discussion on this issue before. I am simulating a VCO test-bench with inductors extracted using EMX. I have the s-parameter file path entered as a variable for the n-port. When I start the simulation I get this error at the start almost immediately:
Error found by spectre during initial setup.
ERROR (NPORT-1022): Generate lock-file for bbspice process failed.
Interestingly, when I simulate just the inductor n-port by itself with the same s-parameter file as above to get the Q and L, the simulation runs smoothly and I get the expected result. Another thing is that there are some older s-parameter files from last year that run perfectly fine with the above VCO test-bench. I'm not really sure what the problem is so would greatly appreciate some help. Thank you.
