5.2.5. Design Guidelines
The I/O design and placement guidelines are different between AGI 022/027 and AGM 032/039. For example, the OCT calibration block in AGI 022/027 can be used to calibrate the I/O buffers located in the same bank row, but in AGM 032/039, the OCT calibration block can only be used to calibrate the I/O buffers located in the same GPIO-B bank only, except for DDR4 DIMM implementation.
When migrating from AGI 022/027 to AGM 032/039, you must re-plan your FPGA and board interface design by adhering to the I/O design and placement guidelines available for the AGM 032/039 device. Refer to the related information to know more about the I/O design and placement guidelines for both AGI 022/027 and AGM 032/039 devices.
