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]}};...
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...
