Vivado,verilog语言,case语句,四选一MUX傲晴**傲晴 上传36KB 文件格式 7z VIVADO verilog 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 \( s0, s1 \)。 - 输出:一个寄存器...
EDA Playground lets you type in and run HDL code (using a selection of free and commercial simulators and synthesizers). It's great for learning HDLs, it's great for testing out unfamiliar things and it's great for sharing code. Let's get started You can start typing straight away. ...

In our case, it was not required because we had only one statement. We now suggest that you write a test bench for this code and verify that it works. If you have difficulty, you can check it with following test bench module stimulus; wire out; reg cntrl,in1,in2; mux_case uut(...
所以,Verilog提供了一种从行为级来描述电路的方式——always等过程块。这些过程块可以让我们方便地利用if、case和for循环等高级语法来描述电路的行为,综合器会自动把这些语句块综合成相应的硬件电路。 Practice:Build an AND gate using both an assign statement and a combinational always block. (Since ......
