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 Cadence,
   I am making my system verilog code to be compatible with IUS.
   I have comipled whole code successfully with IUS tool.
   But when i am running the same code ,i am getting this run time error:

irun: 05.83-p003: (c) Copyright 1995-2006 Cadence Design Systems, Inc.
file: ../tests/system/ei_ahb_slave_simple_transfer/test.sv
                Caching library 'worklib' ....... Done
        Elaborating the design hierarchy:
        Top level design units:
                top
ncelab: *F,INTERR: INTERNAL ERROR
-----------------------------------------------------------------
The tool has encountered an unexpected condition and must exit.
Contact Cadence Design Systems customer support about this
problem and provide enough information to help us reproduce it,
including the logfile that contains this error message.
  TOOL: ncelab  05.83-p003
  HOSTNAME: localhost.localdomain
  OPERATING SYSTEM: Linux 2.4.21-37.ELsmp #1 SMP Wed Sep 7 13:28:55 EDT 2005 i686
  MESSAGE: sv_seghandler - trapno -1
-----------------------------------------------------------------
irun: *E,ELBERR: Error during elaboration (status 255), exiting.

This error is not giving any information that why it's giving this error (like file name or the line number).
So i'm not getting because of which syntax or logical or because of any other reason
this error is coming.

Please provide more information about this error.
Let me know in case of any concern you have,

Hi Piyush,
      The only relevant options you seem to have are:

1. Contact support@cadence.com with a sample testcase
2. Try their latest patch (if yours is not the latest)
3. Try and comment-out some portions of your code, do a trial-and-error approach to narrow down the issue.

Sometimes ncelab -messages help - that prints some additional information.

Yeah, an internal error is almost never your fault. Contacting Cadence support is your best bet.

I have been doing a lot of SV testing in NCSIM. I did managed to crash the tool when I did an Array of instance where I had packed arrays as the ports and signals connected to the ports. The culprit dealt with my use of .* and the by switch to .name or .name(name) I was able to work around the issue.

I checked the LRM and this doesn't appear to be illegal. I also checked the Cadence docs, and didn't find any references to this construct being unsupported. I would suggets trying the recently released 6.1 version. If no luck with 6.1, I would suggest making a small test case and sending to your local Cadence AE or Cadence Customer support. It appears to be an case which
is not supported and should be. ~jm

Hi Piyush.

If you need a fast response, you should submit bug reports direct to support@cadence.com, or to your local AE, or through the support web site at http://sourcelink.cadence.com/. That would ensure that your problem is properly logged in the support system and is given the right priority.

Just posting to a public forum doesn't guarantee that Cadence customer support will see the problem...

Regards,
Steve.
