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

Is there a way to get continous waveforms of DUT signals in Xtreme?
Any help in this regard will be highly appreciated.
Thanks.

Hi DGill,

The way to get waveforms for the DUT signals on the Xtreme platform when running in SW mode is to do a $dumpvars and debug using the post-process mehod. Similarly the HW waveforms can be generated using the VCD on Demand (VoD) feature after the simulation has been run once and use the post-process method.

The Xtreme platform does not support the continuous waveform feature. If you need help in generating VoD waveforms do let us know.

One way to generate continous waveform of a limited number of DUT signals in Xtreme is to $export_read the signals of interest.

initial
begin
$export_read();
$export_read();
...
end

and then use regular $dumpvars for those signals at runtime. This is only available if you using $rcc(run) mode.

One should not use more than few hundred signals in this way or it will impact runtime perfomance.
