摘　　要：PXI Express是一种高数据带宽的总线,并拥有多种高速差分时钟和触发信号;为了设计具有广泛适用性和易用性特点的PXIExpress接口,采用了高集成度、高性能的内嵌PCI Express IP硬核的FPGA作为本方案的核心控制芯片;PXI Express接口的逻辑部分采用了Qsys设计流程完成了针对各种不同应用情况,并具有不同功能和性能特点的接口逻辑子系统,以及相关IP核的设计;最后组建测试平台进行了测试,测试结果表明设计的PXI Express接口能正常工作。PXI Express is a high data bandwidth bus and it can provide high speed differential clocks and trigger signals. In order to re duce the complexity of the design, in this paper, the selected scheme adopts high performance FPGA with embedded PCI Express hard IP core to achieve the design of PCI Express interface. The Qsys design flow is introduced into FPGA logic design to present a series of interfa cing logic subsystems aiming at various applications and all related IP cores. At last, a test platform is set up and the test result shows that the whole design is functional.
