Ensuring the correctness of computer systems used in lifecritical applications is very difficult. The most commonly used verification methods, simulation and testing, are not exha...
Higher-order pushdown systems (PDSs) generalise pushdown systems through the use of higher-order stacks, that is, a nested “stack of stacks” structure. These systems may be us...
- Current industry trends in system design -- multiple clocks, clocks with arbitrary frequency ratios, multi-phased clocks, gated clocks, and level-sensitive latches, combined with...
In this paper we demonstrate a potential extension of formal verification methodology in order to deal with time-domain properties of analog and mixed-signal circuits whose dynamic...
The Automated Production Systems (APS) are composed of concurrent interacting entities. Then any model should exhibit parallel and sequential behaviours. The Grafcet is now well e...
