I don't think there is a board package built up for hw cosim for this board. You may have to make one to build the hw cosim block. Look at the sysgen users guide for details on using the Board Description Builder and make a board package. It should be pretty straight forward as far as specifying the clock and pin location, the parts on the board, etc.
