driver构造的时候引用interface和gen2driv,它的main函数负责把mailbox的内容经过自己肚子转道手给到interface,从而将数据放去DUT。 monitor的话,由于我的DUT是个比较复杂的计算状态机,根据计算的内容不同它实现的时间也会不同,所以暂时只是通过testcase调用monitor的main函数来从interface取计算结果,并且将计算结果通过句柄...

SystemVerilog adds a powerful new port type to Verilog, called an interface. An interface allows a number of signals to be grouped together and represented as a single port. The declarations of the signals that make up the interface are contained in a single location. Each module that uses t...
program可以看做是软件的部分,所以program中不能出现和硬件行为相关的语句,比如always、module、interface,也不能出现其他program的例化语句。program中可以发起多个initial块,也可以定义新的变量。 program的内部变量赋值方式,应该采用阻塞赋值(模拟软件行为),program内部在驱动外部的硬件信号时应该采用非阻塞赋值(硬件方式)。
(5)initial过程块可以在module、interface和program中使用。。对于过程块的书写方式,请记住用begin…end将其作用域’包’住,这一建议同样适用于稍后提到的控制语句、循环语句等等,初学者可以将其对应于C语言中的花括号{ },方便记忆。 3.2 函数 function
// Execute always block whenever value of "a" or "b" change always @ (a or b) begin [statements] end 1. 2. 3. 4. always中的@(event)敏感列表是为了描述硬件信号的触发行为。 所以说,always过程块是用来描述硬件时序电路和组合电路的正确打开方式,因此只可以在module或者interface中使用。
This example shows how to generate SystemVerilog direct programming interface (DPI) and universal verification methodology (UVM) components from MATLAB® functions using built-in templates. This example also reviews the generated SystemVerilog and how it relates to the template. This example...
