module count4(clk,reset,out);
  input clk,reset;
  output [3:0]out;
  reg [3:0]out;
  wire clk,reset;
  always @(posedge clk)
  begin
         if(reset)  out<=4'b0000;
         else out<=out+4'b0001;
  end
endmodule //'include "count4.v"; module count4_tp;
  reg clk,reset;
  wire out;
  parameter DELY=200;
  initial #DELY clk=0;
  initial #DELY reset=0;
  count4 mycount(.clk(clk),.reset(reset),.out(out));
  always #DELY clk=~clk;
endmodule 为什么out没有输出啊??? 还有就是 为什么'include 这个不能用？用的时候有这样的错误提示：* Error: E:/Wordspace/work/count4/count4_tp.v(1): near "'i": Illegal base specifier in numeric constant.
** Error: E:/Wordspace/work/count4/count4_tp.v(1): near "'i": syntax error, unexpected "BASE", expecting "class" 求高手指教！！！
