Count15

Build a 4-bit binary counter that counts from 0 through 15, inclusive, with a period of 16. The reset input is synchronous, and should reset the counter to 0.

module top_module (
    input clk,
    input reset,      // Synchronous active-high reset
    output [3:0] q);
	
 
    always @ (posedge clk)
        if(reset == 1'b1)
            q <= 4'b0;
   	 	else if(q == 4'd15)
        	q <= 4'd0;
    	else
            q <= q + 1'd1;
    
    
            
    
endmodule
