本文介绍了作者对Altera公司可编程逻辑器件的开发与设计的实验系统。该系统有数码管、发光二极管等多种指示器件和一路扬声器输出，提供固定品振和可变RC振荡信号源。输入有打码开关和激动开关等形式，并可提供微动开关硬件去抖电路。芯片外引脚为84脚（全部引脚可扩展），现场可编程。系统主要为学习可编程逻辑器和数字电路提供实验，也可作为相应芯片的开发系统。
This article describes the author of Altera’s programmable logic device development and design of the experimental system. The system has a digital tube, light-emitting diodes and other indicators and all the way speaker output, providing a fixed product vibration and variable RC oscillator signal source. Enter a code-coding switch and excited switch and other forms, and provide micro-switch hardware debounce circuit. Chip pin 84 feet (all pins can be extended), field programmable. System mainly for the study of programmable logic and digital circuits to provide experiments, but also can be used as the corresponding chip development system.
