A Design of Digital Tube Driving Chip Automatic Testing System Based on FPGA

Facing the issues of high testing machine cost, poor reliability of testing algorithms, and complex operation interface in the ATE testing of digital tube driver chips, this paper proposes an automatic testing method for digital tube driver chips based on FPGA. With FPGA testing boards as the core, a digital tube chip automatic testing system is designed and built, which can achieve functional testing of I

C serial interface digital tube driver chips and return test results. Samples are selected for testing, and the output waveform of the chip is displayed through an oscilloscope and compared with the ATE machine testing results. The consistent test results validate that the automatic testing system for digital tube driver chips designed in this paper can be used for industrial screening tests.
