Detailed Description

main VME traffic switch; instatiates the tri-states; must be in the global partition

This module instantiates the tri-states (so will be pushed to IOBs) Busses from all the hierarchy below drive the tri-states if at least one of the registers below drives the bus request signal (no arbitration attempted!!). If there are no requests then the tri-state is configured as an input and drives the down-going bus.
