How to measure bus utilization in hardware

Hi All,

I have an SOPC builder project (using the Video Processing suite) working in silicon.

I would like an indicator of "how much bus bandwidth" is being used at various points wired out to a GPIO so I can see how much capacity I have left for real (I have done the spreadsheets to predict bandwidth etc.)

Its a video project, so simulating takes a long long time (need to run for lots of ms).

I am using the Avalon-MM bus, wondered if there is a "recommended way" to wire out the bus_req/bus_wait sort of signals to a GPIO without going in and editing the sopc VHDL output each time.

Any pointers?

Thanks
