Since electronic Equipment was first developed, static electricity has been a source of problems for users and designers. In the last few years, however, electrostatic discharge (ESD) has become a source of major problems. This has occurred because newer electronic devices, such as integrated circuits, are much more susceptible to ESD problems than previous devices, such as vacuum tubes. Another trend compounding this ESD susceptibility problem is the spread of sophisticated Equipment into home and office environments where ESD is quite common.

音頻管理組件(Audio Management Unit，AMU)是先進客艙娛樂與服務系統(Advanced Cabin Entertainment Service System，ACESS)的組成部分，應用于飛機上音頻資源的管理與控制。飛機運營對航空機載電子系統準確性、復雜性和安全性的高要求，使得其維修維護工作極大地依賴于自動測試設備(Automatic Testing Equipment，ATE)。本課題來源于實際工程項目， FPGA技術具備多種優點，將其與民航測試設備結合研制一個用于檢測AMU故障的自動測試系統，該系統將對AMU自動完成部件維修手冊(Comvonent Maintenance Manual，CMM)所規定的全部功能、性能方面的綜合測試。 本文首先概述音頻管理組件、自動測試系統及其在民航領域的應用，并闡述了課題的背景、研究目標和相關技術要求；文章對可編程邏輯器件CPLD/FPGA的結構原理、硬件描述語言VHDL的特點以及MAXL+plusⅡ軟件的設計流程進行了說明，重點闡述了基于FPGA的DDS信號發生器以及數據采集卡的設計實現、并著重闡述了ARINC429總線的傳輸規范，和基于FPGA的ARINC429總線接口的設計與實現。在ARINC429接口設計中采用自頂向下，多層次系統設計的方法，用VHDL語言進行描述。在發送器中利用了FPGA內部的分布式RAM創建異步FIFO，節約了FPGA的內部資源和提高了數據傳輸速度；在接收器中采用了提高抗干擾性的優化設計。測試結果表明基于FPGA的設計實現ARINC429總線數據通信的要求，使用方便，可靠性好，能夠克服HS-3282芯片中的數據格式固定，使用不夠靈活方便，價格昂貴的缺點。

Abstract: Perfection is relative and application specific. The perfect race car is not the car we use to commute to work. We need products for everyday use that are high quality, affordable, and solidly reliable. There will be times when we must use components that are not perfect, and this is when calibration becomes important. Calibration techniques reduce tolerances in imperfect manufacturing Equipment while maintaining affordability.

Digital convergence, in recent history, has been prevalentin the consumer Equipment domain and the designengineers in this area have been struggling with a plethoraof emerging standards and protocols. What lessons can welearn from their struggle? The same dilemmas now existin in-vehicle telematics and infotainment systems but withthe added issues of extremes of temperature, safety,security, and time in market.

Precision 16-bit analog outputs with softwareconfigurableoutput ranges are often needed in industrialprocess control Equipment, analytical and scientificinstruments and automatic test Equipment. In the past,designing a universal output module was a daunting taskand the cost and PCB real estate associated with thisfunction were problematic, if not prohibitive.
