摘　　要：为了灵活地实现VPX系统中功能的扩展,设计了一种采用PCI-e总线和PCI-x总线的XMC/PMC功能载板。该载板通过P1-P6连接器与不同功能板卡连接,由HD68接口实现外界与载板之间数据通信,并介绍了以PCI-e开关模块和PCIe转PCI-x模块为主的系统方案。对其中的转换模块、开关模块、存储模块、电源模块和时钟模块进行了详细介绍。在电路设计过程中,通过仿真保证高速电路的信号完整性。最后通过与AD板卡进行调试,验证了XMC/PMC设计可行性。In order to flexibly realize the function expansion in VPX system,the design uses PCI-e bus and PCI-x bus to complete the function of XMC/PMC carrier board.The carrier board is connected with different function boards through the P1-P6 connector,the data communication between the outside and the carrier board is realized by the HD68 interface,and the PCI-e switch module and the PCI-e switch PCI-x module are mainly introduced system solutions.The converting module,the switch module,the power module and the clock module are introduced in detail.In the circuit design process,the simulation is to ensure high-speed circuit signal integrity.Finally,by debugging with the AD board the XMC/PMC design is verified feasibility.
