SIMULATOR DEVICE AND SIMULATION METHOD

PROBLEM TO BE SOLVED: To effectively perform debug operation with reduced loads during simulation.SOLUTION: A simulator device simulating operation of a target model in which a plurality of function blocks 100, 200, and 300 are connected to each other through interface terminals comprises: an observation module 400 that includes a plurality of input terminals to be connected to interface terminals and monitors the status of the interface terminals connected to the input terminals; connection management tables 500 and 510 recording association between a terminal identification name assigned to each interface terminal of the function blocks and an observation terminal name assigned to each input terminal of the observation module; and control sections 600 and 601 controlling connections between the interface terminals and the respective input terminals on the basis of records in the connection management tables.
