| Summary: | 碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 102 === This work refers to traditional STB testing system and the equipment and software integration of NI PXI (National Instruments PCI eXtensions for Instrumentation) to design a automation STB testing platform with FPGA (Field-Programmable Gate Array), which fully utilities the FPGA re-programmability, flexibility of pins and various I/O (Input and Output) interfaces. Traditional STB testing system needs a lot of manpower to operate, and it’s fixtures are unique to each STB, not being able to share with any other STB at all. It results in a lot of equipments and resources management issue and a higher manufacturing cost. We use FPGA as a core to develop a multiple STB compliant fixtures with the integration and automation of testing flow to minimize the need of set up time and manpower. The FPGA is used to control peripheral equipments, voltage measurements and frequency measurements with a special consideration of testing pins arrangement as early as any STB starts the design. This FPGA-based STB automation testing platform can be applied to most of STB testing items. From experimental result show that the proposed method reduces 1 ~ 2 testing stations, at most 38.26% time saving and 37.5% manpower saving in three STB models.
