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

This may be unique to the 220 series that I use at home. I used this command (padstack replace) with Allegro Designer at work yesterday and it appeared to work properly.

I tried both commands to fix some pads in a symbol....

The refresh command (refresh all padstacks) refreshed one pin only and would not refresh the other pins.

The replace command seems to replace one pin randomly, but not the other pins.

It appears to be working right for me on 15.2 using PCB Design Studio 220. If one gets refreshed, all get refreshed.

Are all your padstacks the exact same name? Maybe you haven't modified all of them at home. Make sure your PADPATH variable is set to where your pads are located.

I'm pretty sure my paths are set properly but I will double check this weekend.

One other note.....I use XP pro at home and win2k at work. Could it be a problem with XP?

Don't think so. I'm using XP Pro also with one of the latest 15.2 ISRs. Make sure all your padstack names are the same. Possibly you edited an instance instead of the definition creating a different padstack name. Good Luck!

But that doesn't explain why padstack refresh didn't refresh all pins initially. I modified the padstack in Pad Designer, saved it (same name), then tried to refresh all padstacks in Symbol Editor. It only refreshed one pin (it was visually noticable because I made the hole significantly smaller). I then recreated the symbol and saved it, then refreshed the symbol in the brd file and it refreshed OK there. That's when I opened the symbol again and tried the padstack replace command.

Maybe it's just not updating the graphics in Symbol Editor.

I tried this on my system and it worked fine. Did you check the refresh_padstack.log file for possible reasons??

No, I didn't but I'll be sure to when I try it again.

Paths are fine.

I had this problem once before and if my memory serves me correctly, both components have alpha-numeric pin #'s and both components and padstacks were extracted from a brd file using export library.

I even tried to replace the current padstack with a padstack of a different name...... same thing, it replaces one pin randomly. I have to keep running the command till all pins are replaced.

I did notice one thing, when I query the pins (before they get replaced), under the padstack name it says [i](derived from: )[/i]. I assume this has something to do with the symbol being extracted from a brd file.

There is a problem here....trust me :)

It sounds like you have edited some padstacks so the padstacks are not the exact same name. If the padstacks are the exact same name, you should open a new Service Request with Cadence to determine what the problem is.

Also SourceLink solution 1835340 may be helpful.

Title: Dump libraries to create library data and there are extra layers in the pads.
