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

In my design I see after Route (nano & wroute) congestion due to the placement which was unseen before. The trial route -effort high showed no indication. Playing around with the amoebaplace cutsequence it comes out that I reached a quit better result in terms of congestion. Does anybody saw before and faced similar problems ?

Your subject line should read:
Final Nano route congestion missed BECAUSE trialroute -highEffort used.
( HighEffort avoids congestion at all costs )
The best way to analyze congestion is to use trialroute -lowEffort and clean this up as much can.
Then proceed to trialroute -mediumEffort ( the default ) for your optimization runs.
