The invention relates to the technical field of real-time embedded system equipment security analysis, in particular to a firmware hosting analysis test method and system based on advanced abstraction layer simulation. Function information in a binary executable file of target firmware is extracted; a firmware real-time operating system static library file and a function name compiled by the static library file are obtained, a real-time operating system library function used by target firmware is extracted based on the function name, a preset equivalent function is used for replacing a corresponding library function in the target firmware, and the preset equivalent function is a rewriting function equivalent to the function of the corresponding library function; based on the simulator, analyzing and testing the function in the target firmware to obtain a target firmware analyzing and testing result. The firmware simulation test process is executed according to the mapping relation between the firmware and the
