摘　　要：采用两级结构设计了一种4×4SDXC矩阵,用以实现四路不同STM-1输入信号的完全无阻塞交叉连接。整个设计采用FPGA设计方法,阐述了SDH数字交叉连接矩阵的交换实质,重点解析了空分交换单元和时分交换单元的结构框图。最后,采用Quartus Ⅱ软件进行功能仿真,验证了设计的正确性。In the paper, two-stage structure design of 4×4 cross-connect matrix is introduced, and the matrix is used for realizing the non-block cross-connect of four input STM-1 streams.In the design,FPGA flow is adopt- ed. The exchange essence of the cross-connect matrix is described first. And then the diagrams of the space exchange unit and the time exchange unit are analyzed emphatically.Finally, the design is verified using Quar- tus II to verify the correctness of the design.
