AMS simulator - how to save real variable

Cotomaznamenat

Hello,

I would like to save all result of simulation including real variables defined as vector. Variable is defined in Verilog-AMS code and used in analog part of the description.

real sin_corr[Ncorr-1:0];

I'm runing AMS simulator from ADE. In Save option menu I have specified to save all nets (digita and analog). Is there an option which forces simulator to save also variables definedlike vector?

Thanks for help

Adam

 

  • Hi Adam,

    Using the "saveahdlvars=all" switch (on the Outputs form, it's called "Save AHDL variables" does not work for vectored real variables. So the only way of doing this that I know of is to run in "Interactive (debugger)" mode on the Netlisting and Run Options form, and then in SimVision navigate to the module in question and mark those to be plotted or probed.

    You could probably do it via a Tcl input script too with the same settings you do during using Simvision.

    Regards,

    Andrew.

  • Hello Andrew,

    thank you for such a quick reply. I have tried to create probe to vectored real variable (both to whole vector and also to component of the vector). In both cases I have ended up with this error.
    ncsim: *E,DBOBBD: Cannot create SHM probe for mixsim_lin_damp_test_2._CORR.cos_corr[0].
    I don't have to much experience with Simvision. I have used the Simulation -> Create Probe

    Regards

  • Hi Adam,

    That's odd, because I tried it myself and it worked OK. Then I did some searching and found CCR 1450428 which reports the problem you're seeing. I tried the testcase in that CCR and see the problem. I can't spot what is different about my case which works and the one on the CCR which doesn't.

    So probably best if  you contact customer support - clearly support for this is limited to some situations (but I don't know what they are!)

    Regards,

    Andrew.
