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,
I am using a tcl input file for running the ncsim after doing VAP in Palladium TBA. All of the commands and comments, literally evrything in the input.tcl file is echoed to the ncsim prompt which is very annoying. Tcl itself doesnt do this so is there a switch to turn this off?

Thanks,
Hemanth

Instead of passing the tcl commands as a file of commands that get executed just as if you typed them in, pass the commands in via a source command.

Example:

% ncsim -input "@source file.tcl"

You can get more information under "Providing Interactive Commands from a File" in the "Cadence NC-Verilog Simulator Help" document near the end of Ch 9.

Hi Tim,
That wont work as my commands in the script are for palladium and not for ncverilog.

If you are calling ncsim (as opposed to calling saDebug) to do your run then Tim's method does work.

If using the .ncsim.csh example script that VAP produces you will have some difficulty due to shell variable handling, but you can execute it once with the -echo option and modify the resulting output as Tim describes to get your desired result.

Note that output before the "@source" will not be suppressed.

Hi,
I tried it but for some reason the simulation hangs or doesnt progress or whatever. The put all the qt commands in a tcl file and source it in the script which ncsim runs. In the tcl file I have all qt related commands like loading memory and memory dump etc. I also do the 'run' from the tcl file and exit but it gets stuck with no simulation having run and I have to kill it.


Regards,
Hemanth

I also have some conditional if-else statements in the tcl file.
