    Hi,

    Is it possible to bind individual instances of an array of instance via
    configuration to different modules.
    If so then how to explain the last two points of the terminal connection
    rules of the array of instances.

    Thanks
    Kausik
     

    The terminal connections for an array of instances shall follow these rules:
    - The bit length of each port expression in the declared instance-array
    shall be compared with the bit
    length of each single-instance port or terminal in the instantiated module
    or primitive.
    - For each port or terminal where the bit length of the instance-array port
    expression is the same as the
    bit length of the single-instance port, the instance-array port expression
    shall be connected to each
    single-instance port.
    - If bit lengths are different, each instance shall get a part-select of the
    port expression as specified in
    the range, starting with the right-hand index.
    - Too many or too few bits to connect to all the instances shall be
    considered an error.
