通用移位寄存器 通用移位寄存器可以载入并行数据,左移,右移,保持;它能够实现并-串功能(先载入并行数据后移位),也可实现串并功能(先移位后并行输出)。 //Listing 4.8 moduleuniv_shift_reg #(parameterN=8) ( inputwireclk, reset, inputwire[1:0] ctrl, inputwire[N-1:0] d, outputwire[N-1:0] q )...

3、Simple Examples 我们来看一些简单的例子,首先是打印Hello World,毫无疑问这段代码是不可以综合成电路的,这里简单看一下就行。 下面这个例子展示了使用三种方式实现Mux,我建议用第一种,即使用assign。这三段代码生成的电路是一模一样的,但是我们可以看到,out有的被声明成了reg,有的声明成了wire。但实际上其对应...
