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

Hello all,
In the Constraint Manager connected to Allegro Expert 14.2, after I creating a match group in Net->Routing->Relative Propagation Delay wooksheet, adding some pin pairs to this new match group, and setting the scope, delta:tolerance and target, I close the Constraint Manager.
I open the Constraint Manager again. I change the target to another pin pair in that match group, then I find the attribute ""parentGroups"" of the old target disappeared.
What's wrong?


Thanks.
Tom

Wow! 14.2 is real old now... :)

You may want to run Tools > DBdoctor to make sure there is nothing strange in the database.

If that doesn't help, you may be forced to move to a later release (15.2 or 15.5) since 14.2 is not supported anymore plus you can take advantage of new features in these releases.

Sorry I don't have a better answer for you. Maybe someone else does. Good Luck!
