How to save value of global parameter in Spectre

svcher

Hello,


Is there a way to save value of a global parameter in Spectre?

For example, below I use global parameter "fo" to define frequency of AC simulation.  Can I save it together with other simulation results, like current through "v1" in this example?  Is there syntax similar to HSPICE's ".print par('fo')"?

Thanks!

======================================

c1 (1 0) capacitor c=1e-15

v1 (1 0) vsource dc=0 mag=1

parameters fo=1e6

ac1 ac freq=fo

save v1:n

======================================

    Yes, you can use the "info" analysis in spectre. If you just want it to appear on the screen, you can put:

    params info what=parameters where=screen

    in the netlist. Or where=logfile to appear in the log file, or where=file (and optionally file="file.txt" to change the default file), or you where=rawfile in which case it will save it in a  database you can open in ViVA.

    See "spectre -h info" for more details.

    Regards,

    Andrew.
