逻辑分析仪是最重要的数据域测试仪器之一,随着数字技术和计算机技术的发展,逻辑分析仪获得了广泛的应用和快速的发展。因此,结合我国国情,利用虚拟个人仪器的概念,我们研制了以微型计算机为基础的,性价比很高的ELA4521(基于PCI总线)型逻辑分析仪。本文介绍了逻辑分析仪的基本工作原理和硬件结构,重点阐述了ELA4521逻辑分析仪的数据采集通道、触发识别、存储器读写控制、PCI接口和驱动程序的设计。其中,触发识别和存储器读写控制部分采用可编程逻辑器件实现,PCI接口部分采用PLX公司的PCI总线专用接口芯片9030,驱动程序采用KRFTech公司的Windows驱动程序制作工具WinDriver编写。论文的最后还介绍了硬件电路的调试方法及过程。
Logic analyzer is one of the most important data domain test instruments. With the development of digital techniques and computer techniques, logic analyzer has a widespread application and gets a rapid development. Therefore, basing on the situation of our country and the concept of virtual instrument, we developed the instrument ELA4521(based on PCI Bus) logic analyzer, which is competitive. Firstly this thesis expatiated the work principle and the hardware construction of logic analyzer. Secondly the paper expatiated the point on the data of the collects ,the passage and trigger to identification, the read and write control to memory, design of PCI interface and the driver. Among them, trigger and identification and the control of memory were realized by programmed logic device. The interface of PCI was adopted the special chip9030 of PLX company. The driver procedure adopted WinDriver tools of the KRFTech company. Finally the thesis introduced the debugging of hardware.
