The invention discloses a semi-physical simulation test system, relating to the device test technology field. The semi-physical simulation test system comprises a behavior simulation processing module, a standard simulation module, a simulation processing background module, and a comprehensive adapter module. The behavior simulation processing module outputs a simulation equivalent signal according to an excitation signal parameter of a determined device to be detected; the standard simulation module performs standardized simulation processing on received simulation equivalent signals through Matlab/Simulink, and uses the standardized simulation signal to excite the device to be detected through the conversion of the comprehensive adapter module; the simulation processing background module collects simulation signals which is the feedback of the device to be detected through the comprehensive adapter module, performs simulation data counting and processing on the feedback simulation signal and provides the feedback of the processed signal to a behavior simulation processing module to correct and respond the output simulation equivalent signal. The system has the functions of the signal excitation and the automatic responding, produces a specific debugging operation environment to the device development process and satisfies the test verification needs in the device development stage.
