1.5. Debugging the System

Occasionally, the generated system might fail to run or display unexpected behaviors. You can debug the hardware and software system to pinpoint the root cause and ultimately return the system to normal. Optionally, you can also apply the debug tools to view a processor system's inner workings and running mechanisms while on-the-fly.
