Re: [Iverilog-devel] do while loop syntax.

[Lonnie L G. <lg...@sr...>]

What is the earliest version of iverilog that has –g2009 support I tried it with .9.6 on centos and it only has g2005? Is that the latest version on centos?  That’s what I see on centos 6.5.

Are you telling Icarus to use SystemVerilog (e.g. -g2009, -g2012 or -g2005-sv)? The following example runs correctly (displays 0 to 9) using the latest code from git and the -g2009 flag:





module top;
  integer val;

  initial begin
    val = 0;
    do begin
      $display(val);
      val += 1;
    end while (val < 10);
  end
endmodule

 

Since SystemVerilog is not that complete in Icarus it is not enabled by default.

What is the do while syntax for iverilog. I have the loop below that
compiles fine in vcs but errors out in iverilog.

do begin
    @(posedge clk);
    err = $carte_accept(listening_sockfd);
end while (err == -1);

Here are the errors.

Here is the version:

Icarus Verilog version 0.10.0 (devel) (s20140801-15-g4ea512c)

Thansk for the help
