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,
I am trying to write out layer specific routing information of a NET (example: Power net vddx) in DEF format? I am using the "selected" option of defOut but the output DEF has all the layers.
Note:
I am making all layers unselectable.
selectNet vddx
defOut test.def -selected -routing -unit 1000

Any suggestions?

Goal is import the Power Information from one FE database to other. Using FE 7.1_usr2. Are there any dbCommands to get this information?

Thanks for the help.

Hi Vajram,

defOut -selected -routing will output the entire net(s) selected. You can't output just certain layers. I'm curious why you just want certain layers. There may be another way to do what you want.

Hello Kari,
I am trying to get the RDL (ap) layer information (bump to pad connections) of a signal (Core Power) from one database to another database. Some of the blocks are added in the new project and due to timeline of the project, we are trying to avoid re-doing RDL.

Hi Vajram,

I would try something like this. In the "old" database, delete all the metal and via layers you don't want so that all you have are the RDL layer (and possibly a via layer), which you do want. Then use defOut -selected -routing. Do you think that will work for what you want to do?
