hello, i'd like to create a verilog loop that push zero to some register at specific time, and keep on doing so from this point for every equal amount of time (10 cycles for example) . basically it should efficiently replace the following code: initial begin #215327.5 top.dut.timer = 12'h000; #3920 top.dut.timer = 12'h000; #3920 top.dut.timer = 12'h000; #3920 top.dut.timer = 12'h000; #3920 top.dut.timer = 12'h000; #3920 top.dut.timer = 12'h000; #3920 top.dut.timer = 12'h000; end

    This is how I would do it.


    initial begin
       #215327.5;
       drive_reg;
    end

    task drive_reg;
       forever begin
          #3920;
          $display("driving register at %0d", $time);
          top.dut.timer = 12'h000;
       end
    endtask

    thanks, that was really helpful. however, i'd like to make the assignment for a finite number of times... (not 'forever')
