两者的区别在于存储的不同,静态任务调用时共享存储空间,自动任务则为每次任务调用分配单独的栈存储。 systemverilog允许: 在静态任务中声明一个动态的变量 在动态任务中声明一个静态的变量 多种方法声明任务端口 在task中的多条语句不需要begin … end or fork … join语句块 可以任务中间进行返回 可以通过reference,...
74. What is an argument pass by value and pass by reference? 按值传递和按引用传递的参数是什么? 按值传递参数是指将参数的实际值复制一份传递给函数或任务,函数内部的操作不会影响原始值。按引用传递参数则是将参数的地址传递给函数或任务,函数内部的操作会直接影响原始值。按值传递更安全,但效率较低;按...

posedge or negedge. A timing violation occurs if the time interval between an edge-triggered reference event and a data event exceeds the 'limit'. If a reference event and data event occur at the same time, a timing violation is reported. If a 'reference_event' argument is specified without...
Note: It is illegal to use argument passing by reference for subroutines with a lifetime of static. The reason for this restriction is that we are allowed to hierarchically reference the arguments of a task/function as static variables, which are initialized to be zero or specified initialized ...

In pass-by-reference method, a reference to the memory location of the argument is passed to the function or method. Any changes made to the value inside the function or method will affect the original value of the argument. functionvoidabc(refinta,b); ...
