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 queues Qint QueueQ[$]; // same as int QueueQ[$][$]; // associative array of ...
typedef int Qint[$]; // dynamic array of queues Qint DynamicQ[ ]; // same as int DynamicQ[ ][$]; // queue of queues Qint QueueQ[$]; // same as int QueueQ[$][$]; // associative array of queues Qint AssociativeQ[string]; // same as //int AssociativeQ[string][$]; ini...

Dynamic Arrays:run time时得到size;连续内存; Queues Arrays:FIFO/Stack Associative Arrays:离散数据内存,索引可以为数字或者字符串;用于hash 六:结构体 将变量放在一起,比如总线协议放在结构体里;默认是unpacked存放 1:示例 使用:Instruction_Word.address = 24'hF00000; 2:packed存放(加入packed关键字) 第一个数...
除了在设计中使用静态数组,SystemVerilog还提供了动态数组、关联数组(associative array)和队列(queues): AI检测代码解析 int cmdline_elements; // # elements for dynamic array int da[]; // 动态数组 int ai[int]; // 以整数位索引的关联数组
Example - Queues module queue_data(); // Queue is declated with $ in array size integer queue[$] = { 0, 1, 2, 3, 4 }; integer i; initial begin $display ("Initial value of queue"); print_queue; // Insert new element at begin of queue ...
This process can be resource-intensive, especially with large queues, as it involves moving a significant number of elements within the data structure. delete方法从队列中删除一个项目,将所有后续元素向下移动一个位置以填补缺口。这个过程可能会消耗大量资源,特别是对于大型队列而言,因为它涉及在数据结构内部...
Example - Queues module queue_data(); // Queue is declated with $ in array size integer queue[$] = { 0, 1, 2, 3, 4 }; integer i; initial begin $display ("Initial value of queue"); print_queue; // Insert new element at begin of queue ...
The output given below shows that each element of the array was assigned to a value equal to that of its index. Simulation Log ncsim> runarray = '{'h0, 'h1, 'h2, 'h3, 'h4}ncsim: *W,RNQUIE: Simulation is complete. Dynamic Arrays/Queues ...
Queues provide a convenient way to model certain hardware behaviors. This article takes a look into what is behind the new SystemVerilog datatype and how you can use it in your environment. [More...] SystemVerilog Assertion You have heard the buzz, now see what's inside. SystemVerilog Asse...
