Save specified output option in ADE XL transient simulations not working

LMendolia

Hi,

I am running many transient simulations on a schematic by sweeping global variables in ADE XL. All I want to get out of these is a single transient trace per simulation.
I am however noticing that, in addition to the output signal specified in ADE XL, all transient node voltages are also saved. This results in unmanageable disk usage and severely reduces the number of simulations I can run in one go. The transient traces I care about amount to around 500MB when exported to a .tran PSF file, but the entire simulation results take up roughly 100GB.

I tried preventing all node voltages from being saved by changing the "Select signal to output (save)" from allpub to selected (and even none, just to try) in the "Save all..." menu of ADE XL's Outputs pane as well as in the Test editor (I also unchecked/set to None everything else in that menu). Still in the Test editor, I also set the Transient simulation output save option to selected, but none of these did anything as I'm still seeing significant disk usage and all the node voltages in the Results Browser.

Is there anything else I could try to get rid of this unnecessary data? Many thanks in advance for your help.

  • Hi,

    some time ago we changed the default behavior of Spectre if no voltage signal is selected as output. In this case Spectre saves "allpub". Please have at least one Voltage
    in the outputs or use this new Spectre option:   

    * New Option:

    saveselectedtoallpub = default/nooutput

    * Help description:

    Defines when save=selected switches to save=allpub. default ... save=selected will automatically switch to save=allpub if there were no node voltages is saved. nooutput ... save=selected will not be automatically switched to save=allpub if there was any waveform to be saved. Possible values are default and nooutput.

    This should work with Spectre 21.1 ISR7 onwards.  There is no gui switch for it yet so you can put it into the "Additional Arguments" field.

    Kind regards,

    Marc

    Hi Marc,

    Thank you, this was indeed the problem! The only signals I was saving were in fact currents.

    I cannot get the saveselectedtoallpub=nooutput option to work as intended as my Cadence installation is running Spectre 19.1 ISR14, but saving a voltage alongside the desired currents is a temporary solution.

    Best regards,
    Loris
