Verilog Frequency Divider [patched] Info

module one_hz_enable ( input clk_50m, rst_n, output reg one_hz_pulse ); reg [25:0] count; always @(posedge clk_50m or negedge rst_n) begin if (!rst_n) count <= 0; else count <= (count == 49999999) ? 0 : count + 1; end always @(posedge clk_50m) begin one_hz_pulse <= (count == 49999999); end endmodule

To get 1 Hz from 50 MHz: divide by 50,000,000. This requires a 26-bit counter (2^26 ≈ 67M). Using a clock enable pulse every 50M cycles avoids generating a 1 Hz clock signal; instead, a 1 Hz enable strobe is used. verilog frequency divider

A frequency divider can be implemented in Verilog using various techniques, including: module one_hz_enable ( input clk_50m, rst_n, output reg
