摘　　要：针对目前IC测试系统中对PCI接口外设的动态可扩展应用需求,提出了一种基于桥芯片PCI6540透明桥模式的通用PCI-X/PCI总线扩展方案。采用可编程逻辑器件CPLD及Verilog硬件编程语言实现模式控制及传输状态监控功能,并根据PCI总线规范设计了通用扩展平台板卡。通过对扩展板的系统集成及应用,测试验证PCI-X总线扩展平台,测试结果表明该扩展板功能完备、性能可靠稳定,现已应用于国产化芯片测试系统。In view of the dynamic extensible application requirement of PCI interface peripherals in IC test system,a general PCI⁃X/PCI bus extension scheme based on the bridge chip PCI6540 for transparent mode is proposed in this paper.Using CPLD and Verilog hardware programming language to realize the function of mode control and transmission state monitoring,and a general expansion platform board is designed according to PCI bus specification.Test and verify the PCI⁃X bus expansion platform by system integration and application of the expansion board,show that the expansion board has fully functions,reliable and stable performance,and has been applied to the domestic chip test system.
