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

When I run conformal on a relatively large design with about some 1500 mapping points it sometimes crashes with the core dumped. What should be done in such circumstances.

Thanks
Prasad

Hi Prasad

The most common cause is trying to synthesize the RAM's. The tool then runs out of memory at either 'read design' or 'set system mode lec'.

The solution is to do 'add notranslate module ' before 'read design' so the guts of the RAM don't get generated.

If your case is different then please send your log and the .lec_dump_stack file to support@cadence.com, after trying with the latest release (06.20-s200 currently).

Hi Chrystian,

Thanks for your valuable inputs. My case is different from the one you mentioned. I am using the product version 6.1 only. The tool crashes when comparing and due to a single mismatching key point. I dont have access to the latest version. What can be done??

Thanks
Prasad.

Hi Prasad

You should have been contacted by Customer Support. Please work with them to resolve this.

Thanks,
Chrystian
