Design suggestions
Power supply design: The core power supply is recommended to have a maximum copper layer of ≥ 100 mm² to ensure stable voltage.
I/O Bank isolation: I/O banks of different levels should be independently powered and grounded to avoid interference.
High-speed transceiver lines: LVDS/DDR signals should be routed in differential pairs, with attention paid to impedance control.
Temperature management: Try to lay the hot-dip copper layer and keep the core and package temperatures within a safe range.
Configuration and Debugging: It is recommended to use Platform Cable USB or JTAG-SMT for downloading and online debugging.
