OS test system

The invention discloses an OS test system which comprises an MCU module, an FPGA module and a chip IC to be tested, wherein the MCU module comprises a PC end software communication module, a USB communication module, a PMU control module, a TTL interface communication module and an STM32 data communication module; the FPGA module comprises a test channel selection module and an FPGA data communication module; the USB communication module is used for achieving physical connection between a PC end software communication port and a STM32 data communication port; and the PC end software communication is used for displaying chip related information detected in a working process of the OS test system. By the adoption of the OS test system, the cost for detecting an integrated circuit chip IC isreduced; the problems of large size, complex control program, high cost and the like of universal test equipment are solved in an actual production process; and the flexibility of production test andthe SITE number of a paral
