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.
I'm having problems migrating from DC to RC in terms of reading HDL files.

1. I have a directory with subdirectories which include .v files - when I specify the main directory as the HDL search path, RC doesn't read the .v files under the subdirectories - any idea why?
The manual says it works like the search in unix therefore I don't understand why it doesn't try to read the subdirectories.
2. I have .v files which have commands like `include ../../ - when running RC, RC moves to a directory of its own with no regard to where the command was run from (unlike DC where if I run it from a certain directory, this directory is the reference for finding other files in case I use realtive statements such as ..) - therefore, those realtive `include commands doesn't work - any idea how to solve the problem?

Thank you in advance,
Adi.

adi_j,
As you have surmised, RC will not look at subdirectories recursively to find the HDL files, you will have to specify each subdirectory in the hdl_search_path attribute in order to get RC to look for source code in those directories. As for your second question, make sure that when you set the hdl_search_path attribute, you include "." in the path, otherwise the relative paths will on search for HDL starting at the places you specify in hdl_search_path. So in order to get these to work, do the following:

set_attr hdl_search_path {. /home/my_proj/hdl_dir_name}

Hope this helps.
