SystemVerilogDynamicArray 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...
When you copy a fixed-size array to a dynamic array, SystemVerilog calls new[] constructor to allocate space, and then copies the values. 29,You can take even more shortcuts with declaring routine arguments. The direction and type default to “input logic” and are sticky, so you don’t...
unpacked array typedef 下面是一些注意点: enum 不能被直接支持,实际上会被解释为enum type关联的类型 在exported DPI subroutine里, 声明形参为dynamic array容易出错 SV data的实际内存结构对于SV是透明的。Function的返回值必须是small values: void, byte, shortint, int, longint, real, shortreal, chandle,...
