I want to measure the frequency of a signal in verilog. How must I do it?

check below link its helpful to you.

Thanks a lot! I translated the file in verilog to measure frequency's between 1kHz and 5kHz. The main clock of my digilent board is 5O MHz. I don't use the error code, because the in_clock frequency won't be greater than the main clock.

module METING(
input in_clock,
input clk50M,
input reset,
output wire LED1,
output wire LED2,
output wire LED3,
output wire LED4
);
reg [15:0] cnt;
reg [15:0] p_cnt;
reg [15:0] f_measurment;

always @ (posedge clk50M) begin
cnt if (reset) begin
cnt end
end
always @ (posedge in_clock) begin
if (p_cnt f_measurment end
if (p_cnt > cnt) begin
f_measurment end
p_cnt end
assign LED1 = (f_measurment>12000) ? 1 : 0;
assign LED2 = (f_measurment>16000) ? 1 : 0;
assign LED3 = (f_measurment>24000) ? 1 : 0;
assign LED4 = (f_measurment>48000) ? 1 : 0;
