Sample Code: Here is a simple code to implement a counter on the Cyclone IV FPGA:

vbnet

module counter (
  input clk,
  input rst,
  output reg [7:0] count
);

always @(posedge clk or negedge rst) begin
  if (~rst) begin
    count <= 8'h00;
  end else begin
    count <= count + 1;
  end
end

endmodule
