Abstract Digital circuits are widely utilized in computers, because they provide models for various digital components and arithmetic operations. Arithmetic a subclass of that used to execute Boolean algebra. To avoid problems like the infamous Pentium FDIV bug, it is critical ensure correct. Formal verification can be determine correctness circuit with respect certain specification. However, c...

This paper presents an approach for model extraction, formal specification, verification and repair of the scheduler Contiki, which is event-driven lightweight Operating System Internet Things (IoT). We first derive a state machine-based abstraction scheduler’s modes operation along with control flow abstractions most important functions. then use set transformation rules to formally specify al...
