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,

Design->Report->Summary... ("summaryReport") contains this information. Here is some sample output:

==============================
Floorplan/Placement Information
==============================
Total area of Standard cells: 469511.230 um^2
Total area of Macros: 297703.134 um^2
Total area of Blockages: 0.000 um^2
Total area of Pad cells: 587500.000 um^2
Total area of Core: 708425.222 um^2
Total area of Chip: 2286264.955 um^2
Effective Utilization: 3.9201e-01
Number of Cell Rows: 167

The "Total area of core" should be equal to the row area of the block unless unless you've cut rows from the design.

"queryPlaceDensity" might also be helpful. But be aware that it calculates the available area by subtracting the things that take up placeable area (like FIXED hard macros and placement obstructions) rather than simply returning the area of the rows. The intent here is to give you a feel for how hard it is going to be to place the standard cells in the design within the available area.

I don't think there's a natively defined TCL command that returns only the area of the rows in a design, but it would be relatively easy to write a short script that did. Please reply back if that would be helpful.

Hope this helps,
Bob
