HDLBits/Building Larger Circuits/Counter with period 1000(Exams/review2015 count1k)

Build a counter that counts from 0 to 999, inclusive, with a period of 1000 cycles. The reset input is synchronous, and should reset the counter to 0.




module top_module (
    input clk,
    input reset,
    output [9:0] q);
    always@(posedge clk) begin
        if (reset)
            q=10'd0;
        else if (q==10'd999)
            q=10'd0;
        else
            q=q+1;
    end
endmodule
