多片FPGA系统互连结构研究

本文在分析现有多FPGA系统互连拓朴结构的基础上，指出其最佳形式，即硬布线和可编程布线相结合，优势互补，并提出了一种新的拓朴结构——最大权生成树与交叉开关相结合，详述了其设计流程和算法。

The Routing Architecture of Multi-FPGA Systems

The optimal pattern of the interconnect architecture for multi-FPGA system is suggested on the basis of analying the presenting architectures.This pattern uses both hard-wired and programmable connections.We advice a new architecture of maximum weight spanning tree and partial crossbar and intro-duce its design flow and routing algorithm.
