    hi

    i have a problem when trying to use Xilinx hard-macro (NMC) file.

    I need to use a bus module (with tri-state buffer), "bm_4b_v2p.nmc".
    Goal is to use the bus module to connect two other modules.

    What I did was
    - to make a package file (bm_4b_v2p_pkg.vhd) to declare the
    "bm_4b_v2p.nmc"
    - to compile the "bm_4b_v2p_pkg.vhd"
    - to include "use work.bm_v2p_pkg.all; "
    - to instantiate in the top module.

    No compilation/simulation errors occurred, but the bus module is not
    working properly.
    It seems that the bus is not connecting two modules.

    If someone has same experience, let us know how to shoot this problem,
    Thankyou
