This paper presents a new version of critical (feared) scenarios derivation tool ESA PetriNet (extraction scenarios algorithm from Petri net) available from: http://www.laas.fr/ESA. ESA PetriNet allows to derive scenarios leading to critical (feared) situation. In the past version of the tool hybrid aspect (both discrete and continuous dynamic) of system is tacked into account by temporal abstraction. In the version presented in this paper, the system model is given by a hybrid Petri net (differential predicate-transition Petri net) and the hybrid model is directly considered (without temporal abstraction). The algorithm implemented deals with both continuous and discrete dynamics. Furthermore, generated scenarios are minimal (only necessary events). Only necessary information is provided to designer.
