Problem with mailbox.get()

archive

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 [7:0] data);
  begin
    bit  [7:0]  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.
