1:表达 type name[constant]; 一维:int a[16]; 多维:int array[0:7][0:3]; int array[8][4]; 2:unpacked arrays byte,shortint与int都存储在32位里,longint存储在64位;unpacked数组中,如果数据没有占用32位/64位,仍占用32/64,浪费空间。 3::packed arrays 说明:bytes是32位的,通过bit[3:0][7...
A structure differs from an array, in that an array is a collection of elements that are all the same type and size, whereas a structure is a collection of variables and/or constants that can be different types and sizes. Another difference is that the elements of an array are referenced ...
例如在上面的例子中,这一特性就使得我们能够更加容易地从32bit向量中选择字节(byte)。 2.5 数组(非压缩数组) Array (unpacked arrays) SystemVerilog允许声明线网,变量和用户自定义类型(见Section 2.6)的一或多维数组。数组维数在数组明后面声明。下面是两个例子: 通过索引号(index number)来选定数组中的某个元素:...

但是对于验证维度来说,system verilog终于拯救了大家,oop曙光终将照耀大地~covergroup、assert、rand的引入逐步开始拓展出了随机验证,以至后面VMM/OVM/UVM的验证方法学。
