Answer:
// Code your design here
module clk_div
#(
parameter WIDTH = 7,// width of register
parameter N = 100// value of division here 100
)
(clk,reset, clk_out);
input clk;
input reset;
output clk_out;
reg [WIDTH-1:0] r_reg;// counting register
wire [WIDTH-1:0] r_nxt;
reg clk_track;// clock value
always at(posedge clk or posedge reset)
begin
if (reset)// reset
begin
r_reg <= 0;
clk_track <= 1'b0;
end
else if (r_nxt == N)
begin
r_reg <= 0;
clk_track <= ~clk_track;
end
else
r_reg <= r_nxt;
end
assign r_nxt = r_reg+1;
assign clk_out = clk_track;
