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'M using cadence SOC encounter 5.2 with libraries from artisan. After importing my design I get warning & error as: **WARN: (SOCLF-58): Cell 'ANTENNA' has been found in DB so only antenna data will be loaded. Any other data will be skipped. **WARN: Module is not defined in CDUMP/LEF files. It would be treated as an empty module. Reading timing constraint file '.sdc' ... **WARN[line 17]: Skipped invalid point Sclk(clock pin) ERROR: Cannot find 'clocks' that match 'Sclk' (File .constr.1920.pt, Line 9) . ==> ERROR: Can't get clock definition for clock '' (File .constr.1920.pt, Line 9) . Info: read_dc_script finished with 0 WARNING and 2 ERROR . **WARN: Input Transition Time will be transferred from 0ps to 0.1ps inside FE. Please let me know in detail how to remove it. Thanks!

If user wants to turn off all the messages in FE, the following command can be used.
encMessage {warning | info | debug} {0 | 1}
For example: Following command turns off all warning messages:
encMessage warning 0

For this specific lef antenna check, you can disable this check using the following line before importing your design:
set dbgLefInDisableAntennaCheck 1

For this variable 'dbgLefInDisableAntennaCheck', I had this information directly from Cadence support.
There is no real document to fing such variables.
In the soceDBAref.pdf there is some dbg* commands but nothing about variables.

A tric I use intensively in encounter, when I look for a command or a variable, I try this TCL command
info command
info vars
It is very usefull.
