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 using ius 62 and found problem with mailboxes
This is the part of the code using the mailbox.get() in a task under a class :

task txCompare(bit Ε:0] data);
  begin
    bit  Ε:0]  org_data;
    tx.get(org_data);
    if (data != org_data) begin
      $write("%dns : txCompare : Error : Expected data %x, Got %x\n");
      ........................
      ........
And this is the Error of compilation :

ncvlog: *E,BADRFA (../sv/uart_sb.sv,22|18): invalid ref argument usage because actual argument is an automatic variable. 
[unimplemented].

Can someone help me pliz,
Thanx a lot,
ford

This is where nchelp comes in handy.


% nchelp ncvlog BADRFA
        This task or function call actual argument cannot be connected to the
        specified formal reference argument because of the provided reason.
        E.G. Passing entire automatic arrays by reference is not supported,
        when the array is defined within a function. Move the array definition
        out of the function, or enclose the array within a class.

Moving the org_data declaration out of the task scope gets rid of the error.
