In this thesis, the boundary scan technique is discussed in detail and a boundary - scan test system based on computer is also developed. the main contents can be summarized as follows : 1. the ieee std 1149. 1 boundary scan testing standard is researched, and the mathematical description model and some basic theorems of boundary scan testing process is analyzed subsequently
論文的研究內容及主要工作包括: 1 、對邊界掃描技術的基本理論和方法進行了分析和研究，並對邊界掃描測試過程中的數學描述模型以及邊界掃描測試的基本定理進行總結，為邊界掃描測試生成演算法的研究以及邊界掃描測試系統的開發奠定基礎。 -
Secondly, the composition and function of expander board is introduced, the paper describes a detail developing process of selecting component, design interface circuit, protract pcb with protel and design pci interface logic and user ' s logic. with ahdl and max + plus. in addition this paper discusses how to debug pci board, and give the simulation waveform and the result of debug. on the base of all functions is ture, this paper introduce the config registers and memory of bu - 61580, realize the interrupt function and communication based on mil - std - 1553b
首先分析了擴展板的組成、功能，對pci介面邏輯和擴展板的內部邏輯進行詳細設計，並根據其資源要求進行器件選擇，然後使用protel工具進行電路板的製作。另外，本文還介紹了擴展板的調試方法，給出了邏輯模擬波形和調試結果。在此基礎上，本文闡述了協議晶元的配置方法，實現了1553b通訊擴展板間的通訊及中斷功能，達到了開發技術指標。
