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 All,
I want to get the pin location of a certain instance [Pad] in the design? Are they any dbCommands to accomplish this?
Thanks for the help.

There's several ways to go about getting this information from the db, and I'm not exactly certain from your question what object type you're seeking. It sounds like it is a pin on an IO cell (there can be multiple of course) but at any rate, here are a couple of examples that might help. If they don't, please feel free to post back seeking clarification: 

Using dbGet style (debuted in 7.1):
selectInst IOPADS_INST/Ptdspip15
encounter 2> dbGet selected.instTerms.name
IOPADS_INST/Ptdspip15/PAD IOPADS_INST/Ptdspip15/C
encounter 3> dbGet selected.instTerms.pt   
{264.12 1316.13} {251.455 1082.22}

Using FE-TCL (long standing db access mechanism):
encounter 9> set inst [dbGetInstByName IOPADS_INST/Ptdspip15]        
0x18ee84ec
encounter 10> dbForEachInstTerm $inst term {Puts "[dbTermLoc $term]"}
528240 2632260
502910 2164440
(these values can be converted to microns with "dbDBUToMicrons")

Excuse me for not being clear. Yes, I am looking for pin location of a pad instance. Thanks for the suggestion Bob. FE-TCL is great and it works. I will also try the new dbGet.
