SystemVerilog的接口(interface)允许我们将信号声明信息封装于一个地方。下例同上例一样,只是用了interface。现在如果要在两个模块间添加一个信号,或事更改向量长度(size)的话,就只需要修改一处代码了。 看上例中的mod_a,它的端口a1被声明为了interface端口类型(port type),而非传统的input,output或
参数化类(parameterized classes)允许类模板接受不同的参数,从而创建具有不同特性的类实例。这种机制类似于C++中的模板类,使得同一段代码可以根据不同的参数生成不同的类实现。参数化类广泛应用于验证环境中,以提高代码的灵活性和可重用性。例如,可以通过传递不同的约束条件来生成不同的随机激励。 21. How to gener...
I can't quite read the examples you posted. In any case, we're using Parameterized SystemVerilog interfaces now in Vivado. We're still tweaking our use-cases - the latest release of Vivado (2015.3) is supposed to include some better support.

Parameterized cache: Instead of having statically sized caches, you can parameterize your cache to be able to use the same cache module in different parts of your design. You can parameterize the size and the number of sets, or also the number of ways or how many cycles it responds in. ...
