Name of the DeviceInterface block must be unique, not more than one block must have the same name. If multiple blocks found to have the same name then the following error will be thrown.
"VisualSim.kernel.util.IllegalActionException: Architecture_Setup:addBlockReference():: Duplicate Block Reference.
