Designs that use the Generic Tristate Controller component without a Tristate Conduit Pin Sharer might become unresponsive in Qsys (Beta) testing

Designs that use the Generic Tristate Controller component without a Tristate Conduit Pin Sharer might become unresponsive in hardware and in simulation. Tristate conduit masters do not function correctly because the controller loops back the request signal onto the grant signal. An affected system generates messages similar to the following:

Warning: Found combinational loop of 8 nodes.

Add a Tristate Conduit Pin Sharer component between the tristate conduit bridge and any tristate conduit controllers, even if no pins require sharing.
