Dear Sirs,

I am trying to find out dynamic power consumed by my multiplier. So i want to generate a vcd file. I am using the following codes in my verilog test fixture


initial begin
$dumpfile("invchn26.vcd"); // Change filename as appropriate.
$dumpvars(0, generator);
$dumpall;
$dumpflush;

end

But vcd file remains empty. Sometimes the file is created and sometimes not. Pls help if there exists any alternative to generate vcd file . I m a novice.Pls explain in detail
 

Can you change the 0 to 1 and tell me what you got?

Dear amraldo,

I replaced with 1 but it does not make any difference. Is there any other way i can find dynamic dissipation of my multiplier. I have made it power efficient by reducing switchings. I am using xilinx ise. Simply using xpower shows dynamic power to be 0.
