Unexpected activity on a tri-state address bus

Hi Pszemol,

This activity is legal as per Avalon; just as long as the accesses are not qualified with chipselect! Address and data bus values can be driven by what a master is doing with some other slave. Obviously for a tri-state bus, this will not be true of the data lines as they should be held high-impedance unless explicitly driven by an Avalon master accessing something on the bus. For other signals such as address/read/write, however, the signals from other bus transfers will show up on those signals.

Hope this helps.
