3.3. IP Debugging Features
For lite variants with Debug features on, you can read back any values you write to the control IMG_INFO registers.
Debugging features with full variants allow you to query details of received image information packets. Every time an IP receives an image information packet, the image information fields are stored in a debug IMG_INFO register bank. You can read back this information over the memory-mapped control interface.
In a system that is not behaving as expected the debugging features are a useful debugging tool. If required, when the system is working, the IP can be regenerated in Platform Designer with debugging features off so that the design does not add the area cost of the debugging register bank.
