Packed Array / 压缩数组 packed array直译为『压缩数组』,比如在上例中所声明的B, Hex [LEN*4-1:0] B; 它虽然是包含了LEN*4个Hex元素,但事实上它等价于 logic [LEN*4-1:0][HEX-1:0] B; 你可以将其视为多维数组,但是当你在赋值时,如果使用了这种方式(假定B的声明使用了默认参数) B <= 16'h...
(unpack)非合并数组:将数组大小的定义放在等式右边 bit [7:0] bytes [4]; //4个字节,这个仍是合并数组,但是4个存储空间不连续,这是非合并数组 unpacked array会被认为是一个vector,packed array会被认为是一个scalar。 unpacked array的声明有两种方式: 1. int array [0:7][0:31]; array delaration usi...

We have used struct packed to define a packed data structure. This means that the data structure can be packed into a single vector, 15,Constraints direct the random generator to choose values that satisfy the properties you specify in your constraints. Within the limits of your constraints, th...

压缩(packed)数组,灵活访问连续比特流数据 1压缩数组的维度写在数组名的前面。 2bit、reg或wire类型的矢量变量通常被称为一维压缩数组。 3两个维度不同但总长度相等的数组a和b可以进行整体的赋值和比较。 4moduleautomatictest; 5initialbegin 6bit[31:0]a=32h89abcdef; ...

The new dynamic array types facilitate behavioral modeling and assist in the development of verification environments. Semaphores and mailboxes are sometimes used in advanced verification methodologies such as OVM and VMM Data organization Structs & assignment patterns Packed & unpacked arrays Array ...
