摘　　要：随着计算机性能的提高和计算机技术的发展,许多应用领域对系统的带宽和功耗提出越来越高的要求。传统的VME64x总线受制于传输带宽的限制已经不能适应相关技术的发展。因此,为了实现高速数据传输及大功率板卡应用,采用新的总线技术已经成为必然的发展趋势。结合VITA系列的设计标准,设计了一种具备高兼容性的VPX背板,对其中涉及的信号完整性和电源完整性进行分析,做出了针对性设计方案,并通过对高速信号仿真及相应的测试验证了设计方案的可行性。With the development of high-performance computer,there are more and more requirements for the bandwidth and power consumption of the system in many fields.The traditional VME64 x bus cannot work well with them any longer due to the limit of transmission bandwidth.Therefore,in order to achieve high-speed data transmission and high-power board application,the adoption of new bus technology has become an inevitable development trend.Based on VITA series standards,a VPX backplane with high compatibility is designed.Analyze the signal integrity problems involved in the backplane,and make targeted design and verity the feasibility of the design through simulation and test methods.
