摘　　要：UM-BUS(动态可重构高速串行总线)是一种基于故障实时检测和动态重构的新型多通道高速串行总线。UM-BUS总线的传输介质为屏蔽双绞线,传输通道采用MLVDS(TIA/EIA-899-2002)信号传送方式,能够支持多个节点设备直接连接。基于传输线理论,采用Hyperlynx建立了UM-BUS总线物理线路的电阻隔离型、电容隔离型、阻容隔离型3种传输模型,并对仿真眼图及实测眼图进行了分析,确定了UM-BUS总线物理链路模型,为进一步研究UM-BUS总线传输系统提供了支持。UM-BUS （dynamic reconfigurable high-speed serial bus） is a real-time fault detection and dynamic reconfiguration based on a new type of multi-channel high-speed serial bus. UM-BUS uses shielded twisted pair as transmission medium, trans-mission channel uses MLVDS （TIA/EIA-899-2002） signal transmission method, supporting a direct connection of a plurality of node devices. Based on transmission line theory, Hyperlynx is used to establish three transmission models of UM-BUS bus isolated physical line ,which are resistance, capacitance isolated and RC isolated. And simulation of the eye and the eye diagram measurement are analyzed to determine the UM-BUS bus physical link model. This work provides support for further study of UM-BUS bus transport system.
