      Hi,

       

      When i am simulating below code iam getting the message above and waveform is not getting opened.

      It would be really helpfull if someone helps me to fix this issue.

       

      program main;

        bit [7:0] data;

        bit clk=0,rst;

       

        property unknown_check;

          @(posedge clk)

            disable iff(rst) $isunknown(data);

        endproperty         

        unknow_property:assert property(unknown_check);

       

        initial begin

          $display("Entered initial to drive data");         

          rst=1;

          #2;

          data=8'h20;

          #20

       

          data=8'hX;

        end

        initial

          forever #2 clk=~clk;

       

       

        initial begin

          $dumpfile("");

          $wlfdumpvars;

          $dumpon;

        end         

      endprogram
