哪位帮我看看这段Verilog代码？运行一下

demonsolar

module
int_div(clock,clk_out);
//I/O口声明
input clock;
//输入时钟
output clk_out;

//参数--分频系数
parameter F_DIV = 12;
//分频系数<<<<-----修改这里改分频系数
parameter F_DIV_WIDTH = 16;

//输出时钟
//内部寄存器
reg clk_p_r;
//上升沿输出时钟
reg clk_n_r;
//下降沿输出时钟
reg[F_DIV_WIDTH - 1:0] count_p;
//上升沿脉冲计数器
reg[F_DIV_WIDTH - 1:0] count_n;
//下降沿脉冲计数器

//分频计数器宽度
wire full_div_p;
//上升沿计数满标志
wire half_div_p;
//上升沿计数半满标志
wire full_div_n;
//下降沿计数满标志
wire half_div_n;
//下降沿计数半满标志
//判断计数标志位置位与否
assign full_div_p = (count_p < F_DIV - 1);
assign half_div_p = (count_p < (F_DIV>>1) - 1);
assign full_div_n = (count_n < F_DIV - 1);
assign half_div_n = (count_n < (F_DIV>>1) - 1);
//时钟输出
assign
clk_out = (F_DIV == 1) ?

clock : (F_DIV[0] ? (clk_p_r & clk_n_r) : clk_p_r);
//上升沿脉冲计数
always @(posedge clock)
begin

if(full_div_p)

begin

count_p <= count_p + 1;

if(half_div_p)

clk_p_r <= 1'b0;

else

clk_p_r <= 1'b1;

end

else

begin

count_p <= 0;

clk_p_r <= 1'b0;

end
end
//下降沿脉冲计数
always @(negedge clock)
begin

if(full_div_n)

begin

count_n <= count_n + 1;

if(half_div_n)

clk_n_r <= 1'b0;

else

clk_n_r <= 1'b1;

end

else

begin

count_n <= 0;

clk_n_r <= 1'b0;

end
end
endmodule
这样语法可以过，功能没时间看
