There is a significant danger of design errors when developing large-scale or complex systems. If the design errors are overlooked and the system is put into service, it can result in situation that is extremely detrimental to society: well-known examples include the power outages that occurred in the American Northeast, failures in the online systems used by banks, and interruptions in mobile phone service. With the extraordinary advances being made in computer technology, it has become commonplace for computers to be embedded in everyday products such as electrical household appliances. It is becoming increasingly important to verify the correctness of the design when developing such logic systems. Conventional design verification methods center on computer simulations of the operation of the system being designed; however, such methods cannot simulate all operation patterns, and there is a high possibility that design errors may be overlooked. I am researching ways to avoid this sort of situation by using mathematical techniques to verify design correctness automatically. Thus far I have succeeded in verifying the designs of parallel computer connection configurations and programs for controlling robots.
