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

hi, all:

I have 2 new questions,

1. following is a script to get all the timing paths in SOCE after buildTimingGraph, but is doesn't work, pls help me! The bold characters is the main command.

proc getDesignPath { } {
 set FILE [open list.tmp w]
 dbForEachHeadPath [dbgHead] dpath {
  set type [dbObjType $dpath]
  if { $type == "dbcObjPath" } {
   puts $FILE "Path: [dbPathId $dpath]"
   dbForEachPathTerm $dpath termPtr {
    if { [dbObjType $termPtr] == "dbcObjTerm" } {
     set instPtr [dbTermInst $termPtr]
     puts $FILE "[dbInstName $instPtr]/[dbTermName $termPtr]"
    } else {
     puts $FILE "[dbFTermName $termPtr]"
    }
   }
  }
 }
 close $FILE
}

2. How to get all the via cells in SOCE, that means to get all the via definitions in LEF tech file within SOCE.

Thanks!

For item 1, there was a good posting on this topic in this forum entitled: "CTE-TCL to get one timing path?"
http://www.cdnusers.org/Forums/tabid/52/forumid/19/postid/4253/view/topic/Default.aspx

As discussed in that thread, the CTE-TCL interface's collection mechanism (ie, "report_timing -collection") returns a collection for all the timing paths reported. Once you have the paths captured as collections, you can use the "timing_points" associated with that collection to get the instances and terminals that you're seeking to get in your example code above.

Here's an example that's more aligned with what you're trying to do I believe:

foreach_in_collection timing_point [get_property [report_timing -collection] timing_points] {
puts "[report_property [get_property $timing_point pin]]"
}

I have a hunch that dbForEachHeadPath only works with the FE timer, and as you're probably aware the tool is using the CTE timer going forward.

For item 2, I'm not aware of a public command available that does what you're asking. I'll post again if I come across additional information that would be useful.

Hope this helps,
Bob
