我们首先按照4位将这个packed array slice进行了解压,然后逆序按照4位重新放回了这个slice中,完成了赋值。我们也能发现,这两个操作符的流出/流入方向,以及它进行的是压缩还是解压,只和它们在左子式还是右子式有关。如果我们调换两个操作符, {<<4{B[LEN*3 +: LEN]}} <= {>>4{B[LEN*3 +: LEN]}};...
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 ...
the declaration of an array is represented by the unpacked array: logic [#bits-1:0] bt1 [#rows-1:0]; or by a packed array: logic [#rows-1:0][#bits-1:0] bt1; and both of these representations can be referenced using the following nomenclature: bt1[a_row][bit_slice] similarl...
