范围随机函数(std::randomize())使得用户能够随机化当前范围内的数据,而无需定义一个类或实例化一个类对象。 范围随机化函数的语法如下: scope_randomize ::= // 没有包含在附录A中 [std::]randomize([variable_identifier_list]) [with constraint_block] 语法12-10 — 范围随机化函数语法(没有包含在附录A...

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...
std是systemverilog的内建包，定义了一些class、task、function和变量 常用的有：function int randomize(...);class semaphore;class mailbox;class process;
// assert(req.randomize()); // ** AVOID THIS if (!req.randomize()) `uvm_error("USER_DEFINED_FLAG", "This is a randomize error"); //req is a class handle in the above exampleBen Cohen http://www.systemverilog.us/ ben@systemverilog.us...
there are 16 million possible combinations. With the constraints, this number of possible solutions reduces so that, for instance, a = 10, b = 2, c = 4 does not satisfy this constraint. If the constraints are such that there are no possible solutions, then, randomize returns with 0 and...
C++中函数指针的用途非常广泛，例如回调函数，接口类的设计等，但函数指针始终不太灵活，它只能指向全局或...
