fork and automatic

sevent

 The followign code does not compile with ncverilog (the file has a .sv extension):

... 
  foreach(i[idx])
  begin
    fork
    automatic string jdx = idx;
    begin
      run(jdx);
    end
    begin
      $display("jdx = %s",jdx);
    end
    join_none
  end
...

ncverilog gives:

 ncvlog: *E,UNSAUT (autoloop.sv,50|23): The 'automatic' keyword is not supported in this context.

  • I haven’t seen the source code where you’ve used the automatic keyword. So it very well may be legal in the context in which it appears. There are several places where it is legal, but our simulator isn’t ready to process it yet. If you are trying to declare a variable local to a task or function automatic, try declaring the function as a whole automatic. I gave an example in the forum thread referenced in the link below.
