Unpacked Array / 解压数组 unpacked array可直译为『解压数组』。如果我们换种方式声明寄存器B, Hex B [LEN*4]; 我们就会得到unpacked array。unpacked array的长度定义写法比packed array更灵活,比如声明长度为64位的数组,可以是[64],也可以是[63:0]或[0:63]。unpacked a
(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...

$display ("unpacked array_1[7] = %b", unpacked_array[7]);//[数组修饰]从大到小和从小到大没区别,都是默认最右边是第0个。 //3.多维数组:两种用循环来赋值的方式 //3-1.for赋值 $display ("array_assignment_in_FOR_method:"); for (int i=0;i ...
