exclude signal using save command for spectre simulation

jasongong

Dear all,

i am trying to exclude signal from a subcircuit when writing a save file for simulation.

the circuit has hierarchy of X1.X2.X3.

where X3 corresponding subckt name is A.

A includes one transistor TN330, which i don't want to save any voltage or terminal current associated with it.

below is what i put into a file and included in the spectre simulation.

save * subckt=A depth=1 exclude=[TN330:*]

save * subckt=A depth=1 exclude=[TN330:*] sigtype=subckt

however, after simulation, i still get output like:

TN330:ids, TN330:ig  etc etc. and many those signals have a small icon of "E".

i am not sure what the correct format should be and hope someone here can help.

thanks

jason

  • Jason,

    It's not clear what you're trying to do here. What analysis are  you looking at the output of? I can't see why this would save any operating point parameters unless it was the dcOpInfo (i.e. a info analysis with what=oppoint) you were looking at - and that's not controlled by the save statements anyway.

    Perhaps it would be useful to see the analysis statements you have in your netlist and also the version of spectre you're using (should show this at the top of the spectre.out log file).

    Regards,

    Andrew.
