probe tcl command with time_window option

apogee

Hi,

I'm running AMS simulation and using probe.tcl file to save the waveform. The size of output file is really big so I need to have an option of only save the waveform during a window of simulation time (i.e. only save waveform from 1us to 2us sim time). 
In Spectre Guide, I found an option for save statement: time_window=[t1 t2] . But I could not find anything similar for tcl probe command option ... 

Thanks.

    You could do this (from a quick experiment by doing):

    run 20us
    probe -create -name dacOut -emptyok -database ams_database {top.dacOut}
    run 15us
    probe -delete dacOut
    run

    I thought this might work, but unfortunately it doesn't:

    probe -create -name dacOut -emptyok -database ams_database {top.dacOut}
    probe -disable dacOut
    run 20us
    probe -enable dacOut
    run 10us
    probe -disable dacOut
    run 5us
    probe -enable dacOut
    run 10us
    probe -disable dacOut
    run

    Anything fancier, you'll probably need to contact customer support.

    Andrew.
