Hi
I have a ep4ce6 fpga board and I am trying to make a counter that counts up to 2_999_999_999.I don't know why it's not working. Here is the code: (I am trying to make a 1 sec timer) What am I doing wrong. I am selecting a verilog file in
the Quartus Application. The code compiles but led does not light up every second.
module mycounter
(
input clk, //50MHz onboard clock PIN 23
input reset,
output led
);
reg [25:0] counter; //26 bit - count up to 50_000_000 to generate 1 sec
reg tmp;
//COUNT
always @(posedge clk)
if(~reset)
counter <=0;
else
counter <= counter + 1;
//COUNT Comparator
always @(*) tmp = (counter == 26'd49_999_999);//
assign led = tmp;//I want the led to light up every second - IT DOESN'T ???
endmodule
Thanks
Saleem

If your led is lit for just 1 clock period of 20 ns you won't see it.
