原理图

参考链接
https://github.com/wjcdx/jchdl/blob/master/src/org/jchdl/model/gsl/example/Mux4.java
1.创建Mux4.java, 并生成构造方法和logic()方法
?
?
2. 根据逻辑原理图，添加输入输出线
?
?
3. 在构造方法中搜集输入输出线并调用construct()方法
?
?
4. 在logic()方法中创建子节点并连线
?
?
5. 创建inst静态方法方便后续使用
?
?
6. 创建main方法执行验证
?
?
运行结果为：
?
?
四种组合逐个选择i0~i3中的值。
7. 生成Verilog
?
?
执行结果如下：
