hi..
does anyone know how to generate a .vcd file in xilinx. i need to calculate the power consumption using xpower analyser. anyone plz help me

 

To generate a .vcd file:

Before you type run on vsim command, type this:



vsim> vcd file vcdtest.vcd

vsim> add -r /*

vsim> run 10ms

vsim> checkpoint

vsim> quit -f

thanks for ur reply. I generated the .vcd file. but i now need to calculate the power consumption for my design. i tried using Xpower analyser in xilinx. but there s no variation n power. i am using xilinx 8.5i n using modelsim for simulation.
