Question

For an unpacked array port, the port and the array connected to the port must have the same number of unpacked dimensions, and each dimension of the port must have the same size as the corresponding dimension of the array being connected.

If the size and type of the port connection match the size and type of a single instance port, the connection shall be made to each instance in an array of instances.

If the port connection is an unpacked array, the unpacked array dimensions of each port connection shall be compared with the dimensions of the instance array. If they match exactly in size, each element of the port connection shall be matched to the port left index to left index, right index to right index. If they do not match it shall be considered an error.

If the port connection is a packed array, each instance shall get a part-select of the port connection, starting with all right-hand indices to match the right most part-select, and iterating through the right most dimension first. Too many or too few bits to connect all the instances shall be considered an error.
