    spectre: fsdb output directly out of ADE Reply

    Hi all

    I'm working on a project based on IC6.1.3 with default MMSIM7.1 (which I can switch up to 10.1)

    and I'm currently facing some large simulations and the waveform viewer is giving me the creeps ...

    Therefore I tried some different formats that can be selected in the ADE Output Menu (sst2, psf ...)

    but postprocessing, zooming and so on are still so sloooowwww. I searched through the

    manual and found the possiblity to write fsdb. 

     

    My problem is, that I get fsdb outputs if I run spectre from the command line with the output

    set to fsdb, but I can't get it to work if I start simulations directly from ADE. I already set 

    SPECTRE_DEFAULTS to -format fsdb but with no success. The switch seems to be

    recognized, it's reported in the spectre-logfile but I don't get fsdb outputs :(

     

    Can someone please give me some pointers on how to get fsdb as a default ?

    At least until 6.15 is coming  with seems to get an all new waveform viewer

     

    Best Regards

     

    Andi

    Andi,

    You might want to take a look at psfxl since that's a faster format which is supported within the environment. You need to be using a recent enough IC613 version (you need at least IC613 ISR14 and MMSIM71 ISR13) - better still IC614 and MMSIM101.

    The trouble with writing fsdb is that various things will break if you use this. That's because ADE expects a format it can read for doing things like operating point annotation and so on. So it's really only supported for a command line flow.

    Regards,

    Andrew.

     Hi Andrew

     

    Thanks for the clarification. I switched to 10.1 and it's a bit faster now. 

    For the big ones I'll switch to the command line and a different viewer

     

    Best Regards
