Re: clock_frequency

`timescale 1ns/10ps

module foo(clk);
     input clk;

     real t0;
     real t1;
     real frequency;

     initial
          begin
               @ (posedge clk) t0 = $realtime;
               @ (posedge clk) t1 = $realtime;
               frequency = 1.0e9 / (t1 - t0);
               $display("Frequency = %g", frequency);
               $finish;
          end
endmodule
