在SystemVerilog中,要创建一个随机位宽的数组,你可以使用动态数组(dynamic array)和随机化(randomization)结合起来。动态数组允许你在运行时动态调整数组的大小,而随机化则允许你生成随机的值。 以下是一个简单的例子,展示如何使用SystemVerilog创建一个随机位宽的动态数组: ```systemverilog class RandomWidthArrayExample...
其次,SystemVerilog提供了类(Class)和接口(Interface)功能,实现了面向对象的设计方法。这种方法使得设计模块的可复用性和可扩展性显著增强。例如,在复杂SoC设计中,可以通过接口统一描述模块间的通信协议,从而简化系统结构。此外,类的引入还使得仿真环境可以使用更高抽象层次的代码来描述行为,从而缩短验证时间。
A dynamic array is an unpacked array whose size can be set or changed at run time, and hence is quite different from a static array where the size is pre-determined during declaration of the array. The default size of a dynamic array is zero until it is set by thenew()constructor. ...
