How to find the transient operating point of MOS device while simulating extracted netlist

Dear All,

We can find the  transient operating point of MOS device (see as below)  with non-extracted or pre-layout  netlist.

But, how it can be done when we are using extracted netlist (spf view of the block).

    Did you ensure that the enabled checkbox is on? Did you make sure that "Where" is "file"? Can you post the line from the bottom of the input.scs where the textinst info statement appears?

    Andrew.

    No idea - I've never seen this behave this way and not write the file (unless the path is wrong - but then I'd expect warnings in the log file). As I keep telling you, this would be better handled via customer support.

    Regards,

    Andrew.
