From Google:

Mod-13:

Code:`define TICK #2 module mod13Cntr(clk, reset, Q); input clk, reset; output [3:0] Q; reg [3:0] Q; //Behavioral Code for a Mod-13 counter always @ (posedge clk) begin if (~reset) begin if (Q == 4'b1100) begin Q <= `TICK 4'b0; end else begin Q <= `TICK Q+1; end end end always @ (posedge reset) begin Q <= 4'b0000; end endmodule

Code:module mod_n_cntr #(parameter [3:0] n = 'd12)( input clk_i, rst_n_i, output [3:0] cntr_o); reg [3:0] cntr_d, cntr_q; always @ (posedge clk_i, negedge rst_n_i) begin: clk process if (!rst_n_i) begin cntr_q <= 'b0; end else begin cntr_q <= cntr_d; end end always @ (*) begin : comb if(cntr_q == n - 1) begin cntr_d = 'b0; end else begin cntr_d = cntr_q + 1; end end assign cntr_o = cntr_q; endmodule
