4-bit counter X35277

Design a circuit that implements a 4-bit counter (mod 16). The counter must start at zero after reset and increase the value at each cycle.

Specification

module counter4(count, clk, rst); input clk, rst; output [3:0] count;

Input

• clk is the clock signal.
• rst is the synchronous reset signal.

Output

• count is the 4-bit output of the counter.
