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

We are using the new 15.2 shape editor. We have created all new shapes on this design. On this 12 layer design, we have to turn the shapes to defer filling as it takes too long to add or modify a trace. Then when we make the shapes smooth, it is taking 1 1/2 to 2 hours to smooth! It is the same on both a pc and Unix. Is anyone else having these kind of shape issues on larger designs? This has cost us several days of work on a critical design just messing with the shapes. Any suggestions?

DMaldona,

Without looking at your database this is a difficult question to answer. Your best bet is to contact Cadence customer support and send them the database for R&D to look at.

Unless absolutely necessary, the "use_accurate_delay_calculation" variable should be off. This is found at Setup > User Preferences > Signal_analysis. Cadence should have named this variable "Radically_slow_down_your_system"

I tried attaching a gif, then a jpeg file showing this, (both smaller than 500K) but the system wouldn't let me. Look at http://dcchapters.ipc.org/pnw/slow.jpg to see where the variable is located...

Grumpy,
the file attachments that can be uploaded to the forums must end in one of the following:
exe, .doc, .pdf, or .zip.
