Now My problem
I want start counter up when Press push button from 0 untel 15 binary display on board but my problem why neccessary press push button to increase cunter I want Generate Clock by itself.
I believe My problem in Assinment clock in Quartus II.
Please anyone clear My problem tell me.
my code is
module counter
(
clk,
reset,
result,
ena
);
input clk;
input reset;
input ena;
output [3:0] result;
reg [3:0] result;
always @(posedge clk or posedge reset)
begin
if (reset)
result = 0;
else if (ena)
result = result + 1;
end
endmodule

Hi ALMODAWAN,
your code looks fine to me, but what is your clock frequency ? Who is driving the "ena" signal?
Kind regards
