Many of you already received communications about the move of the Cadence user community into cadence.com. And many of you have already joined, with over 4000 registrations in the first two weeks.

The new Cadence Community enhances the ability of Cadence users to connect and collaborate. In addition to moving the community into cadence.com -- enabling single sign-on for community, Sourcelink and Cadence events -- the new site is organized around nine technology segments, giving you easy access to product information, training, forums and blogs. Some of the new features include:
  • Ability to respond to posts via e-mail
  • Technology-specific blogs
  • Latest Web 2.0 social networking capabilities
  • Public profile options
  • Private messaging
  • Friends lists
Visit the new Cadence Community today at www.cadence.com/community and join the discussions!

Registration note: Due to the scope of the enhancements and the new SSO registration system, we were not able to migrate existing cdnusers.org member accounts. So new registrations are required, but this enables a broader set of functionality we think you'll enjoy.

Forum note: Under the guidance of forum moderators, we have taken the 20+ cdnusers.org forums and consolidated them into 11 forums on the new site. Posts have been brought over so you can leverage that posting history. CDNusers forums will be set to read only starting 7/30, and cdnusers.org will be redirected to the new community on 8/4.

Best regards,
Mike and Tom

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.

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) ΐ.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

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.

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