Clock in testbench

Hi,

Suppose if i want a clock in my module so that it will go to entire design, how will it be written in testbench?

Clock in testbench

always #10 clk = ~clk;

Re: Clock in testbench

hai
clock decleration with out initializing

always #25 clk=~clk

if you want to initialize , then
initial
begin
clk=0;
always #25 clk=~clk
end

The other way of declaration the clock

forever #25 clk=~clk


this is how we declare clock
bye
