How to measure bus utilization in hardware

Honored Contributor II

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?
