    how can NC-SIM generate SAIF file Reply

    Hi all,

       The SAIF file is another form of Switching Activity for Power analysis. but how to generate it by NC-verilog.
       Does there any system tasks can I call in my testbench? I do not find any key words in ncvlog.pdf which is include in CDS documentation.

       Thanks for your help!

    Eric,

    You should be able to use dumpsaif in the same manner you might use dumpvars. If you need it I may be able to come up with an example for you.

    best regards
    Doug

    Hi Doug,

    Thanks!
    According to your help and the syntax about dumpvars. I add dumpsaif in my bench, but the tools don't recognize it.


    : $dumpsaif (1, fetch_tb);
    : |
    : ncelab: *E,NOTSYT (../config/fetch_dumpwave.vh,25|15): Unrecognized system task or function (did not match built-in or :
    : user-defined names) [2.7.4(IEEE Std 1364-2001)].


    What's your mind? I appreciate that you give me an example.


    Regards

    Eric

    Eric,

    My fault, my response was a bit vague.
    Actually dumpsaif is a tcl command but I use dumpvars as an output for signal dumping. I don't know how to attach a testcase here, so if you want to send me some email douge@cadence.com I will send you a small example of how it is used. My example is verilog. I have not tried it with vhdl but I assume it must be similar.

    Best Regards
    Doug

    Eric,

    That's Great. I am glad it helped. I have looked for tcl docs regarding saif but I have been unsuccessfull so far. I am still looking.
    If I am able to locate some useful doc I will send it to you via email.

    Best Regards
    Doug

    You can find the TCL documentation in the [i]NC-Verilog Simulator Help[/i], Chapter 13, [i]Using the Tcl Command-Line Interface[/i].
