Efficient Data Structure for Fully Symbolic Verification of Real-Time Software Systems
نویسنده
چکیده
A new data-structure called DDD (Data-Decision Diagram) for the fully symbolic model-checking of real-time software systems is proposed. DDD is a BDD-like data-structure for the encoding of regions 2]. Unlike DBM which records diierences between pairs of clock readings, DDD only uses one auxiliary binary variable for each clock. Thus the number of variables used in DDD is always linear to the number of clocks declared in the input system description. Experiment has been carried out to compare DDD with previous technologies.

Memory Efficient Data Structures for Explicit Verification of Timed Systems
Timed analysis of real-time systems can be performed using continuous (symbolic) or discrete (explicit) techniques. The explicit state-space exploration can be considerably faster for models with moderately small constants, however, at the expense of high memory consumption. In the setting of timed-arc Petri nets, we explore new data structures for lowering the used memory: PTries for efficient...

متن کاملSafety Verification of Real Time Systems Serving Periodic Devices
In real-time systems response to a request from a controlled object must be correct and timely. Any late response to a request from such a device might lead to a catastrophy. The possibility of a task overrun, i.e., missing the deadline for completing a requested task, must be checked and removed during the design of such systems. Safe design of real-time systems running periodic tasks under th...
متن کاملA Trust Based Probabilistic Method for Efficient Correctness Verification in Database Outsourcing
Correctness verification of query results is a significant challenge in database outsourcing. Most of the proposed approaches impose high overhead, which makes them impractical in real scenarios. Probabilistic approaches are proposed in order to reduce the computation overhead pertaining to the verification process. In this paper, we use the notion of trust as the basis of our probabilistic app...
