概述Xilinx公司的FPGA(现场可编程门阵列)芯片正向高密度化发展，FPGA的内核在提供低成本和高性能的同时还要求低功耗。当今先进的亚微米IC工艺正趋于采用低电压供电,同时这将导致对大电流的不断需求。工程线路板的设计必需满足这类电源供电的需要。现在FPGA的内核和I/O的电源 Overview Xilinx FPGA (Field Programmable Gate Array) chips are evolving toward higher densities, and the FPGA core requires low power while delivering low cost and high performance. Today’s advanced submicron IC processes are tending to adopt low-voltage power supplies, which at the same time result in a constant demand for high currents. Engineering board design must meet the needs of such power supply. Now FPGA power and I / O cores
