function logic [15:0] myfunc2; input int x; input int y; endfunction 在事件表达式、程序连续赋值表达式或非程序语句表达式中调用带有 output、inout 或 ref 参数的函数是非法的。但是,const ref 函数参数在这种情况下是合法的(参见 13.5.2)。 在函数头和 endfunction 之间可以编写多条语句。语句按顺序执行...

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 ...
如果想在routing中改变handles,必须将此routing的argument 生命为ref The core of OOP is to encapsulate(压缩) data and related routines into a class. The calc_crc function in the extended class calls calc_crc in the base class using the

输入输出信号封装为method方法、自动生成握手信号。 可用复合数据类型来组织数据,提高代码可读性和可维护性。 提供各种小型FIFO模块,在构成复杂的弹性流水线电路时,比Verilog更高效。 可用顺序结构、瞬时结构、并行结构构成状态机,相比Verilog手动维护状态转移更加方便。
