When getting started orplanning the board/hardware for the System Monitor/XADC, it is recommended that you read the Application Guideline section of theSystem Monitor/XADC User Guide. There is a section on PCB layouts and recommendations on how to route external inputs. It is critical for the performance of theSystem Monitor/XADC that a correct reference is used. When using an external reference IC, you need to select a reference IC with the correct tolerance (i.e., for Virtex-61.25V 0.2%).
