Temporal Analysis of Time Bounded Digital Systems
To perform veri cation of digital systems with time bounded delays, it is essential to characterize the space of all possible system behaviors. In this paper, we describe our analy...

Improved undecidability results on weighted timed automata
In this paper, we strengthen two recent undecidability results of [9,10] about weighted timed automata, an extension of timed automata with cost variables. More precisely, we prop...
