irun passing real-time data to a running external application

VaclavPeroutka

Hello,

I am thinking about to post-process and show the data from the irun simulator in external application in the real time. For example I generate the screen data sending HDMI and Java/C++/TK/Python app shows the generated screen.

Is there any means how to do that ?

  • Hello, I finally went to C with Xlib. My testbench looks like this:

    module tb ();

       import "DPI" function void init_screen();
       import "DPI" function void deinit_screen();
       import "DPI" function void show_boxes();
      
       initial begin
          #100 init_screen();
          #100 show_boxes();
          #100 show_boxes();
          #100 show_boxes();
          #1 $display( "we should see boxes");

          #10000 deinit_screen();

       end
    endmodule // tb

    and DPI function for show_boxes() :

    extern void show_boxes( void)
    {
      XFlushGC( disp, gc);
      while (1) {
        XNextEvent(disp, &e);
          /* draw or redraw the window */
           if(e.type==Expose) {
      XSetForeground(disp, gc, yellow.pixel);
      XFillRectangle(disp, w, gc, 20, 20, 30, 30);
      XSetForeground(disp, gc, red.pixel);
      XFillRectangle(disp, w, gc, 50, 20, 30, 30);
      printf("boxes on screen\n");
      break;
           }
        // Handle Windows Close Event
        if(e.type==ClientMessage)
          break;
      }
    }

    But when I call this func once no boxes are shown. If I run it twice or three times the boxes are shown but func stays in while() loop. It looks that XEvents are processed strangely. Any idea how to fix the code ?
