Macros usage

Hi All,

Source code:  https://www.edaplayground.com/x/M6gk

code sample:

//////////////////////////////////////////////////

module ex;

  int res;

 

  initial begin

    for (int i=0; i<=1; i++) begin

   `ifndef MODULE1

`define MODULE1

  if (!res)begin

    $display("MODULE First Time");

    res = 1;

  end 

  else begin

    $display("MODULE Second Time");

  end

`endif

      

    end

  end

endmodule

//compile options: How to run two times?

///////////////////////////////////////////////////

As a compilation argument, I am not passing +MODULE1.  So default, it is enabled and I get the "MODULE First Time Display".  Now for the second run, since MODULE1 is already defined, code should not run and no display should come out. 

How to make code runs two times in eda playground?

For the first run, MODULE1 should be defined and for the next run, it should not be enabled. How to do this?

Thank You,

Mahesh
