数字分配矩阵网络及矩阵开关是自动测试系统的重要组成部分,担负着控制信号流的任务,常用于卫星/移动/电信E1/T1信号程控分配调度。采用FPGA作为实现控制逻辑的核心部件,介绍了上位机的软件设计思路和FPGA的内部编程实现及仿真。该方案具有规模大、成本低、高速等特点,可广泛应用于大规模基带数字系统测试及信号程控分配调度中。
The digital distribution matrix network and the matrix switch are important components of the automatic test system and bear the task of controlling signal flow. They are commonly used in the program-controlled dispatching of satellite / mobile / telecom E1 / T1 signals. Using FPGA as the core part of the control logic, introduces the software design ideas of PC and FPGA’s internal programming and simulation. The program has the characteristics of large scale, low cost, high speed and the like, and can be widely applied to large-scale baseband digital system testing and signal program-controlled distribution scheduling.
