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

i have created a symbol (.dra) with pin pad assigned already. Now i want to change my pin pad size. How can i do that?

The method i used is to use Pad Designer (or use Tool->padstack->modify library padstack) to modify the padstack accordingly. This will update the library padstack. The thing is i can't seem to see this padstack update in the symbol file (.dra) after running the "refresh" command. The viewlog give a warning that my padstack (e.g pad70.pad) cannot be loaded.

However, if i goes to my board layout design (.brd) and use "refresh", i noticed the padstack was updated when i try to see the padstack again (using ->modify design padstack).

I quite confused on what is the proper procedure to update/modify an existing padstack so that it will reflect in my symbol file(.dra) as well as the board file(.brd)

Thanks.

Hi wizlogix,

I think it is because your padpaths are not set in user preferences.

Go to Setup, User prefernces, Design_paths, and set the padpath to where you keep your library padstack files.
You can set up multiple paths depending on how you want to organize your libraries/padstacks.

This also applies to the psmpath for the dra/psm libraries.

Hope this helps.

Hi Alan

I have checked my pad and psm design path, they should be correct.

Have anyone else have encountered this before?

Like Alan (kaplanet) says....it's in the setup of your pad path... Also, check to see where the pad (which directory) is being created. The padstack editor typically places the pad in the last opened directory.

Hello wizlogix, after updating padstacks using Tool->padstack->modify design padstack, Click on update to design located at
File-> update to design. It will update the pads in .dra file. Hope it will help you.

Also, pad70 is not a very good name for the .pad file, better name it (file>save as) something more descriptiive like pad60cir30drl.pad then it can't be confused with another pad - especially if using footprints imported from earlier version which are allocated numeric padnn.pad names by default, so if you re-use footprints from another design they end up with nonsense like thru hole IC's with SMT pads... -Phil
