FPGA

I am a beginner in FPGA programming. I wanted to blink LED on my FPGA board. Code compilation was done successfully. So, I programmed it on my DE0- Nano Altera FPGA board. But I could not see the LED...

This is a very generic description of a problem. Can you provide more detail? Did you make I/O pin assignments to connect the outputs of your design to LEDs on the board? Can you provide the HDL code?

    module LED_blink(clk,outp);
    input clk;
    output reg outp=0;

    reg [25:0] count=0;

    always@(posedge clk)
    begin
    if(count<25000000) // blink 1 sec as clk freq is 50MHz
    begin
    count<=count+1;
    end
    else
    begin
    count<=0;
    outp<=outp;
    end
    end
    endmodule

      You're never changing the value of outp. It's always 0.

        I didn't change the output value. That is 0.. Can you help me with this to generate a pulse
