}; // 只是c语音默认，反大括弧后面可以不写分号，加上也不算错 你如果在if ( x>=500 )后面就加;的话，编译系统就认为这句if语句结束了，从而：1.找不到条件 成立时执什么语句部分；2.找不到else部分。因此算是个错误语句。所以，分号不能乱加，只能加在语句之后。你的程序：int main(v...

是不是你第一个else前面多了个分号啊？。。。 还有你最后那个printf语句后少了分号。。。
else if(a!=0)out=2'b00;endendmodule 相关知识点: 试题来源: 解析 加一个使能信号吧,可能是由于out没有赋初值;还有判断的方法最好是使用4‘b0;如:d!=4’b0;把else补全,最后一个else结果一 题目 verilog求助,提示错误(1):near "module":syntax error 求问高手这是怎么了啊?module decder(a,b,c,d...
