Abstract

Design principles concerning the use of FPGA are of particular importance in aerospace applications since the neglect of such design principles can cause catastrophic effects in aerospace system, as it will be explainedin this paper. FPGA design rules such as power conditioning and signal integrity for properly interfacing high speed FPGA with its interface circuits are discussed in this paper as it relates to aerospace systems. Signal integrity to avoid crosstalk within a FPGA has not been a great concern because most of the attention over the years had been on signal integrity at the PCB level. However, this paper shows a real example of crosstalk within a FPGA in an aerospace application.
用于航空航天应用的FPGA布局中的电源和信号完整性研究
关于使用FPGA的设计原则在航空航天应用中特别重要,因为忽视这些设计原则会导致航空航天系统的灾难性影响,这将在本文中解释。本文讨论了与航空航天系统相关的高速FPGA及其接口电路的功率调节和信号完整性等FPGA设计规则。在FPGA内避免串扰的信号完整性并不是一个大问题,因为多年来大多数注意力都集中在PCB级的信号完整性上。然而,本文展示了一个在航天应用中FPGA内串扰的真实例子。
