源代码：

module counter(cout,clk,reset,enable);
input clk,reset,enable;
output[7:0] cout;

wire clk,reset,enable;
reg[7:0] cout;

  always @(posedge clock)
  begin:COUNTER
if(reset==1'b1)begin
  cout<=8'b0000_0000;
end
else if(enable==1'b1)begin
  cout<=cout+1;
end
end
endmodule

点击了命令窗口区的 # Compile of new.v failed with 1 errors.                               # Compile of new.v failed with 1 errors.

就跳出这窗口

说没定义“clock”,这是什么意思呀？谢谢各位啦！！
