    debug current flows Reply

     Is there a way in spectre of AMS-designer to debug current flow?   Currently I'm using AMS interactive with simvision to debug from the top level.  If I see an unexpected current value from a top port, I would like to follow down the hierarchy to see what the major contributor up the hierarchy.  Are there any ways to do this?  Currently I pause the simvision, probe port flows down the hierarchy.  It's a bit cumbersome and I'd like to see a way to do it more elegantly. Thanks!

    Bump!

     

    I would also like to know. if this is possible with voltages, like so:

    set measvoltage #$TB_NAME.Portname

     then how can you access currents using a similar approach and assigning it to a variable.

    adding -flow does not work in the same way it works for probe.

    To the original poster's question, I don't think you can do this any way other than what you've done.

    For Paul's question, you need to use the value command rather than the # shortcut. So:

    set meascurrent [value -flow  PLL_160MHZ_sim.I3.IEXT_25u]

    The "-flow" is important here.

    Andrew.

    Thank you Andrew for the quick reponse,

    I will give that a try.
