初学verilog,在modelsim里编译成功的程序为什么在quartus里编译显示错误呢？module mux_two(out,a,b,sl);
  input a,b;
  input sl;
  output out;
  reg out;
  always @(a or b or sl)
  if(!sl==1)
    out=a;
  else
    out=b;
  endmodule

成长中的原始人

错误不是在这段，WIDTH没有定义吧

回复 2# 成长中的原始人

可是为什么在modelsim里显示编译成功呢

在module上面使用`include"（绝对地址）"引用你定义parameter的文件
