Up-down counter
X53256 en
Design a 4-bit up-down counter (mod 16). The counter must count-up when the input signal
up is 1. Otherwise, the counter must count-down. After reset, the counter must be initialized
at zero.
The top module must be called updown count4.
module
updown count4(up, count, clk, rst );
input
up, clk , rst ;
output
[3:0] count;
Input
• up is the input signal that indicates when the counter must count-up (1) or count-down
(0).
• clk is the clock signal.
• rst is the synchronous reset signal.
Output
• count is the 4-bit output.
