Hi,
I've got the following problem: I've defined a matrix type as
where pixel is a SLV with a given length.
Now I have an entity that takes such a matrix as input (e.g. (2 downto 0, 19 downto 0). Within that entity I want to split that matrix into several submatrices with the same height (2 downto 0) but different width depending on in how many parts it should be split (e.g. 19 downto 10 and 9 downto 0). These submatrices are then the input of several subentities within the top entity. The input ports of these subentities are also of type matrix but with the appropriate size. I then tried to assign the corresponding submatrices by
SubEntIn <= EntIn(2 downto 0, XXX downto YYY);
where XXX and YYY are expressions depending on some index i. This however gives the following error
What am I doing wrong? And what solution would you suggest?
Thanks.

Code:
type matrix is array (natural range <>, natural range <>) of pixel;
where pixel is a SLV with a given length.

Code:
Only one discrete range allowed in slice name of "entin".
Cannot resolve indexed name as type sub-array #1 of work.somepackage.matrix.
