We have extended the ACL2 theorem prover to automatically prove properties of VHDL circuits with IBM's Internal SixthSense verification system. We have used this extension to...
Recently, the model of weighted timed automata has gained interest within the real-time community. In a previous work, we built a bridge to the theory of weighted automata and intr...
This paper investigates a complexity-effective technique for verifying a highly distributed directory-based cache coherence protocol. We develop a novel approach called “witnes...
We present a process algebra suitable to the modelling of timed concurrent systems and to their efficient verification through model checking. The algebra is provided with two con...
We present a refined model for Role Based Access Control policies and define a risk measure for the model, which expresses elements of the operational, combinatorial and conflict ...
