基于SOPC技術設計了一個綜合應用系統：實現了鍵值數據采集、顯示，并將采集到的數據通過串口送給上位機；也可以接收上位機送來的數據，控制點亮相應的二極管且將接收到的數據顯示在數碼管上。系統硬件由FPGA及外圍電路組成，采用了性能優良的Nios II軟核處理器；軟件在Altera公司的軟件集成開發工具Nios II IDE下應用C語言編程。該系統工作可靠，在實際的應用設計中有一定的參考價值。
Methods for designing a maintenance simulation training system for certain kind of radio are introduced. Fault modeling method is used to establish the fault database. The system sets up some typical failures， follow the prompts trainers can locate the fault source and confirm the type to accomplish corresponding fault maintenance training. A training evaluation means is given to examining and evaluating the training performance. The system intuitively and vividly shows the fault maintenance process， it can not only be used in teaching， but also in daily maintenance training to efficiently improve the maintenance operation level. Graphical programming language LabVIEW is used to develop the system platform.
