Question
Write a Verilog Code for 4 Bit Counter and the Counter should Reset at 1110
Solution
Sure, here is a simple Verilog code for a 4-bit counter that resets at the binary number 1110 (decimal 14).
module counter (
input wire clk,
input wire reset,
output wire [3:0] out
);
reg [3:0] count;
always @(posedge clk or posedge reset) begin
if (reset) begin
count <= 4'b0000; // Reset the counter
end else if (count == 4'b1110) begin
count <= 4'b0000; // Reset the counter when it reaches 1110
end else begin
count <= count + 1; // Otherwise, increment the counter
end
end
assign out = count;
endmodule
This code defines a 4-bit counter that increments on every rising edge of the clock signal. If the reset signal is high or the counter value reaches 1110, the counter is reset to 0000. The current counter value is always output on the out wire.
