<p>PROBLEM TO BE SOLVED: To provide a technique for outputting logs that make clear the time sequence of operations performed by firmware and hardware.SOLUTION: A simulator apparatus comprises: an execution unit emulating instructions of firmware, acquiring time information in response to an input/output instruction from the firmware, adding the time information to the input/output instruction, and executing the input/output instruction; a first virtual device outputting first operation information output in a first output form and the time information in response to execution of the input/output instruction to which the time information is added, the first operation information being associated with the time information; a second virtual device outputting second operation information output in a second output form and the time information in response to the execution of the input/output instruction to which the time information is added, the second operation information being associated with the time information; and an integration unit outputting operation history information in which the first operation information and the second operation information are arranged in a time sequence on the basis of the time information.</p> |
