在对比SystemVerilog中的相等运算符之前,先来看一下三种最基本的逻辑运算符,下文中以·表示与运算,以+表示或运算,以'表示非运算。我们都知道在逻辑代数中,只有0和1,那么在SystemVerilog中,对于四值逻辑(0、1、z、x)的逻辑运算结果又会怎样呢? logicv[4] = '{1'b0,1'b1,1'bz,1'bx};initialbeginforeach...
生成语句可以动态的生成verilog代码。这一声明语句方便了参数化模块的生成。当对矢量中的多个位进行重复操行时,或者当进行多个模块的实例引用的重复操作时。或者在根据参数的定义来确定程序中是否应该包括某段verilog代码的时候,使用生成语句能够大大简化程序的编写过程。 生成语句能够控制变量的声明、任务或函数的调用,还能...
I am trying create verilog module that can support parameterized instance name. I understand that the signal width and other such things can be parameterized. But can we also parameterize the module instance name? In following code, I am curious if there is any way ...

function void的应用,SystemVerilog 提供的function void,参数里不但可以是input还可以包括output和inout,使用更灵活规范,可一定程度避免出现只能仿真但不能综合的错误。 实际上相对Verilog而言,SV的改变远比上述要多,但是对可综合部分的增强主要是上述几条,后面我翻译一下Synthesizing SystemVerilog Busting the Myth that...
