Reliability improvement scheme of DDR controller based on FPGA

This article first discusses the DDR3 system calibration principle of the Virtex-7 series FPGA, analyzes the reliability of the DDR3 controller under different temperature and voltage conditions, and then proposes a solution to improve the reliability of the DDR3 controller. Simulation verification and on-board debugging test results show that this solution can effectively improve the reliability of the DDR3 system in FPGA devices under different temperature and voltage changes.
