摘要
SpaceWire总线是一种专门用于空间高速数据传输的新型总线,针对该总线设计的系统芯片是实现高速传输通信的关键,其指标的优劣决定着系统的优劣。以AT7911E为例,分析了该类芯片的结构特点,针对主要参数进行了测试分析,并提出了集成电路自动测试系统与协议功能测试相结合的综合测试方法,实现了芯片全面的性能测试验证,对于SpaceWire系统芯片的测试具有指导意义。
Space Wire is a new bus standard used for high speed data transmission between space instruments. And the system chip designed for it is the key to realize high speed transmission,whose quality determines the merits of the system. Taking AT7911 E as an example, the structure characteristics of the chip are analyzed, and the main parameters are tested. At last, a comprehensive test method combining ATE and protocol function test is put forward, which achieves the overall performance testing and verification of system chip and has the guiding significance for the test of Spare Wire system chip.
