I used the following to get operating point information:

simulator lang=spectre
dcOpInfo info what=oppoint where=file file="op.rpt"

How can I filter the oppoint info to the specified mosfet's? Say,I only want to get the operating point info for the mosfet's of the current mirrors (top.analog_ckt.currentmirrors.m*).

Thanks in advance.

No,it gives you everything. If you want an option to filter it with a
wildcard, please contact Cadence Customer Support and request an
enhancement.

Regards,

Andrew.

Hi, Andrew,
Is it possible for me to save the vdsat, vt, vds, vgs and region (off, triode,...)
of the current mirrors with "save" cmd?

I tried:
1. save *:vdsat devtype=mosfet
2. save m*:oppoint devtype=mosfet

But I did not get new files generated? Where can I locate the "save" result?

Thanks.

This is for if you want to save the operating point data during a swept
analysis (e.g. during a transient, or during a dc sweep). It will add
them into the psf database for the tran or dc analysis.

Note that devtype=mosfet wouldn't work - you'd have to use devtype=bsim4
or devtype=bsim3v3 or whatever type of device you are using. Or use
sigtype=dev instead.

Regards,

Andrew.
