Vivado,verilog语言,case语句,四选一MUX 傲晴**傲晴上传36KB文件格式7zVIVADOverilog 这个模块实现了一个基于两个选择信号的4路选择器,能够从四个输入中选择一个并输出。 1. 输入和输出: - 输入:四个数据输入 \( in1, in2, in3, in4 \) 和两个选择信号 \( s0, s1 \)。

if else与case的区别是if else会综合成一串小mux以体现优先级,而case会尽量用大mux来表示。比如下面这个图,用case写只要一个cell就事办了,用ifelse则需要三个mux。所以除非一定要凸显优先级,我们能用case尽量用case。 以上这点是没有错的,但是要注意一点,lib里面的mux只有单输入与双输入,如果我们要写超过双输入...
