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 am writing an Allegro SKILL program that needs to ignore power nets.  So I first coded it to look for the VOLTAGE property on a net and that worked fine.  Then I specified the VOLTAGE property using the Constraint Manager and now I can't find the VOLTAGE setting in the design in SKILL.   Voltage is "General Property" and can't be put into an ECSET so I don't think the various Ecset SKILL functions will work.

Any thoughts about how to get information from the "General Properties" section of the Constraint Manager?  Or get them back into the design so they are really properties I can find the old way.

Try adding the voltage property to the net(s) instead of adding them as part of an ECSet.
Open the General Properties worksheet in the Nets folder.
You may then use some skill to find the VOLTAGE properties.
For example something like

designnets = axlDBGetDesign() ->nets
ignorednets = '()
count = 0
foreach(xx designnets
   mynet = nth(count++ designnets)
   netprops = mynet -> prop -> ??
   count1 = 0
   if(netprops != nil
      then
      foreach(xx netprops
         pmember = nth(count1++ netprops)
         if(pmember == "VOLTAGE"
            then
            ignorenet = 1
         ); end if
      ); end foreach
   ); end if
   if(ignorenet == 1
      then
      ignorednets = cons(mynet ignorednets)
   ); end if
); end foreach

Thanks. I tried putting it in the General Properties and couldn't see it in the design. I just tried it again and now it works - like I thought it did in the first place.

Weird. I hate it when things don't work as expect - then work as expected.
