3.2.5. Dynamic Reconfiguration
Because of the asynchronous nature of the PHY, you must perform calibration to achieve timing closure at a high frequency. At a high level, calibration involves reconfiguring input and output delays in the PHY to align data and strobes. With the PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP, you can perform the calibration by using dynamic reconfiguration feature. The dynamic reconfiguration feature allows you to modify these delays by writing to a set of control registers using an Avalon memory-mapped interface.
