内建的类随机化方法对类成员变量执行专有的操作。使用类来对需要随机化的数据建模是一种强大的机制,它使得我们能够产生通用、可复用的包含随机变量的对象,并能够产生可以在以后扩展、继承、约束、过载、使能、关闭、以及从其它对象合并或分离的约束。类及与其关联的随机变量和约束在处理上的方便性使得类非常适合描述和...

范围随机化函数的std::randomize() with形式允许用户为本地范围变量指定随机约束。当说明约束的时候,范围随机化函数的参数指定的变量变成了随机变量,所有其它变量被认为是状态变量。 task stimulus (int length); int a, b, c, success; success = std::randomize(a, b, c) with {a < b; a + b < leng...
SystemVerilog assertstdrandomizevariable, SystemVerilog rankpat123 May 27, 2014, 10:53am 1 Hello, Could you please let me know what simulators should do when we use assert(std::randomize(variable)) and assertions are turned off I am using it but bit confused what should simulators do ?
