    International audienceThe formal veri cation has become a recommended practice in safety-critical software engineering. The hand-written of the for- mal speci cation requires a formal expertise and may become com- plex especially with large systems. In such context, the automatic generation of the formal speci cation seems helpful and reward- ing, particularly for reused and generic mapping such as hardware representations and real-time features. In this paper, we aim to formally verify real-time systems designed by AADL language. We propose an extension AADL2LNT of the Ocarina tool suite allowing the automatic generation of an LNT speci cation to draw a gateway for the CADP formal analysis toolbox. This work is illustrated with the Pacemaker case study

Uno de los campos en los que es necesario el uso de sistemas que traten y estudien los datos clínicos de manera precisa es la prevención de enfermedades. Los métodos formales ofrecen el rigor y la precisión necesarios para el modelado del proceso de análisis de dichos datos. En particular, los autómatas fuzzy son muy apropiados en este caso, ya que permiten representar la incertidumbre e imprecisión que se han de tener en cuenta en este tipo de análisis. En este trabajo se propone crear una herramienta gráfica que permita a los especialistas médicos, que son los que tienen el conocimiento clínico, el diseño de estos modelos de análisis de una manera sencilla e intuitiva. El objetivo principal de este trabajo es crear un entorno de diseño de modelos basados en autómatas fuzzy a través de un lenguaje de dominio específico y un editor gráfico para facilitar el diagnóstico precoz de enfermedades.

One of the fields in which it is necessary to use systems that process and study clinical data in a precise way is disease prevention. Formal methods can offer the rigor and precision necessary for the modeling of the process of analysis of said data. In particular, the fuzzy automatons are very suitable in this case, since they allow to represent the uncertainty and inaccuracy which must be taken into account in this type of analysis. In this paper is proposed to create a graphic tool which allows medical specialists with clinical knowledge, the design of these analysis models in a simple and intuitive way. In relation to the main purpose of this paper, it could be stated that it is to create an environment of model design based on fuzzy automaton through a specific domain language and a graphic editor to facilitate the early diagnosis of diseases.
