高级制造技术与更小的工艺尺寸驱动着内核电压向更低的方向发展。这一趋势加上现有的I/O标准，促成了基于FPGA的多路电压轨设计。为了确保系统可靠性，应当对每路电压轨进行监控。ADI公司提供多种电压监控器产品，从简单的单通道复位发生器，到具有业界领先阈值精度(±0.8%)的多电压监控器。随着内核电压的降低，高阈值精度的重要性正变得日益重要。针对XilinxFPGA的多电压监控器产品选型表中列出了每款Xilinx®FPGA系列的内核电压、I/O电压以及辅助电压(可选)的需求。内核电压范围为1.0V～2.5V，I/O电压电平在1.2V与3.3V之间。面向XilinxFPGA的监控设备补充器件指南面向XilinxFPGA的监控设备补充器适合XilinxFPGA的多电压监控器XilinxFPGAsADI多电压监控器件指南XilinxFPGA内核辅助……
