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

If a board has a large (120) pin connector and the vendor has a multiline (fractional) version of the model (say 20 pins for middle of the connector) does it make sense to have them generate a complete 120 pin connector model and then in the layout assign that model to the entire connector?

Or should we work with a section of the mode and move it around depending on the signals we want to model (SE or Diff)?

When we use multiboard design links and we use a Mated connector model.  do we assign the model only to 2 of 3 boards (once per conn) or do I assign the same model to board1board2

board1-[mated conn] [mated conn]--board2--[matec conn]  [mated conn]--board3

side view is:

board1                     board3        
[conn]-motherboard(board2)-[conn]

so my signal goes from board1 to board3 via motherboard.
