Initializing Multiple Altsyncram Instantiations

You first add a mif file to your core. Once done then you can port map the core wrapper manually at instantiation

and 1) either edit each with its file name.

or 2) if you want to use a loop then you can declare a 2D string and call each file name by its index in string:

type name_array is array(1 to 10) of string(8 downto 1);

signal filename : name_array := -- assign your file names here

assuming they are 10 names each 8 characters.
