在SystemVerilog中,联合数组的声明类似于普通数组,但需要使用associative关键字来指定它是一个联合数组。索引类型可以是整数、字符串或其他数据类型。 systemverilog // 声明一个以整数为键,以字符串为值的联合数组 typedef struct { string name; int age; } Person; Person people[string]; // 声明一个以字符串...
SystemVerilog中除了数组、队列和关联数组等数据结构,这些数据结构还可以嵌套。 module top; typedef int Qint[$]; // dynamic array of queues Qint DynamicQ[ ]; // same as int DynamicQ[ ][$]; // queue of q…
