摘　　要：本文阐述了FPGA供电网络的特点及设计方案。FPGA供电网络工作在亚稳态造成了通用输入输出(GIO)模块的工作异常,针对该问题,提出了一种FPGA供电网络工作在亚稳态的解决方案,旨在减小供电网络亚稳态给整个模块正常工作带来的影响,提高模块工作的稳定性。通过优化FPGA复位信号的处理方法,且在供电网络输入输出端分别增加大容量去耦电容,并经实验验证,该方案可有效改善FPGA供电网络的稳定性。The paper describes the characteristics and design of the FPGA power system.The FPGA power system working in metastable state,will causes the GIO module to work abnormally.In response to this problem,a solution for FPGA power system working in metastable state is proposed to reduce the risk of system metastability and improve stability.The paper optimizes the hardware design,adding decoupling capacitors and further optimizes the programmable logic design(PLD).Through simulation and engineering tests,the power system works stably,and the GIO module works without abnormality.
