    Precedence: bulk

    Replace the entire example, including the command line args
    and expected output with the following:

    Examples:

    Given the following Verilog HDL:

    `define STRING reg [1024 * 8:0]

    module goodtasks;
      `STRING str;
      integer int;
      reg [31:0] vect;
      real realvar;

      initial
        begin
          if ($value$plusargs("TEST=%d",int))
            $display("value was %d",int);
          else
            $display("+TEST= not found");
          #100 $finish;
        end

    endmodule

    module ieee1354_example;
      real frequency;
      reg [8*32:1] testname;
      reg [64*8:1] pstring;
      reg clk;

      initial
        begin
          if ($value$plusargs("TESTNAME=%s",testname))
            begin
              $display(" TESTNAME= %s.",testname);
              $finish;
            end

          if (!($value$plusargs("FREQ+%0F",frequency)))
            frequency = 8.33333; // 166 MHz
          $display("frequency = %f",frequency);

          pstring = "TEST%d";
          if ($value$plusargs(pstring, testname))
            $display("Running test number %0d.",testname);
        end

    endmodule

    Adding the following plusarg to the tool's command line:

    +TEST=5

    will result in the following output:

    value was 5
    frequency = 8.333330

    Adding the following plusarg to the tool's command line:

    +TESTNAME=bar

    will result in the following output:

    +TEST= not found
     TESTNAME= bar.

    Adding the following plusarg to the tool's command line:

    +FREQ+9.234

    will result in the following output:

    +TEST= not found
    frequency = 9.234000

    Adding the following plusarg to the tool's command line:

    +TEST23

    will result in the following output:

    +TEST= not found
    frequency = 8.333330
    Running test number 23.
