extract wavefom characteristics using spectre (commandline)

[pierre13]

Hello !
I would like to extract the wavefom characteristics using spectre simulator (commandline). I don't find the info using straight spectre simulator, so I switch to spice simulator using :

"simulator lang=spice
.EXTRACT TRAN LABEL=timing_info_result YVAL(A, 15n)"

Actually, I would like to size the PMOS versus the NMOS in an inverter architecture. So, I will extract some timing info (rising/falling times...). Here, the extract is a test.

However, I have the issue :

Warning from spectre during circuit read-in.
WARNING (SFE-1805): "input_sizing_MOS_inverter.scs" 51: .EXTRACT is not
recognised as a valid SPICE control card.

commandline : spectre input_sizing_MOS_inverter.scs &

Thanks to help me.

Instead of .EXTRACT , try the .MEAS[URE] command!
