Device simulation is an important method of embedded device security analysis, due to the extensive and heterogeneous nature of the current peripherals, the existing simulation technology for peripheral simulation is mostly fuzzy, to find the input and output that meet the firmware requirements as the main goal. In order to construct a template based on IO interface identification to extend the peripheral simulation scheme, this paper identifies the IO interface without firmware source code based on the characteristics of the IO configuration process in MCU firmware. Through experimental comparison, this method has a certain effect in MCU firmware interface recognition.
