多路选择器mux是数字电路设计中很常见的一种电路结构,平时写verilog也经常会需要用到。 但想象一个场景,输入是256bit信号,输出是8bit信号,选通信号是32bit,如果写一个组合逻辑电路,用case来描述,未免太麻烦了。 就会像这样: View Code 上述方式显得很冗余,因此用for循环来构造mux就更方便了,示例代码如下:(这里实现的4to

Hello everyone. Mux verilog code below. They do the same, but option 2 got huge delays and cannot meet timing. Conclusion: they have different
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. But to run your code, you'll need to sign or log in. Logging in with a Google account gives you access to all non-co...
For the life of me I cannot figure out how to generate a parameterized mux in verilog... I understand how to generate, say, a 4:1 MUX of
