This book introduces state-of-the-art verification techniques for real-time embedded systems, based on the inverse method for parametric timed automata. It reviews popular formalisms for the specification and verification of timed concurrent systems and, in particular, timed automata as well as several extensions such as timed automata equipped with stopwatches, linear hybrid automata and affine hybrid automata.The inverse method is introduced, and its benefits for guaranteeing robustness in real-time systems are shown. Then, it is shown how an iteration of the inverse method can solve the good parameters problem for parametric timed automata by computing a behavioral cartography of the system. Different extensions are proposed particularly for hybrid systems and applications to scheduling problems using timed automata with stopwatches. Various examples, both from the literature and industry, illustrate the techniques throughout the book.Various parametric verifications are performed, in particular of abstractions of a memory circuit sold by the chipset manufacturer ST-Microelectronics, as well as of the prospective flight control system of the next generation of spacecraft designed by ASTRIUM Space Transportation.

This book constitutes the refereed proceedings of the 17th International Conference on Formal Modeling and Analysis of Timed Systems, FORMATS 2019, held in Amsterdam, The Netherlands, in August 2019.The 15 full papers and 2 short papers presented in this volume were carefully reviewed and selected from 42 submissions. The papers are organized in the following topical sections: special session on data-driven and stochastic approaches to real-time, including monitoring and Big Data; timed systems; linear and non-linear systems; timed automata; special session on timed systems and probabilities.

This book constitutes the refereed proceedings of the 21st International Symposium on Automated Technology for Verification and Analysis, ATVA 2023, held in Singapore, in  October 2023. The symposium intends to promote research in theoretical and practical aspects of automated analysis, verification and synthesis by providing a forum for interaction between regional and international research communities and industry in related areas. The 30 regular papers presented together with 7 tool papers were carefully reviewed and selected from 150 submissions.The papers are divided into the following topical sub-headings: Temporal logics, Data structures and heuristics, Verification of programs and hardware.

Quand vos vibrations changent, tout ce que vous attirez change et, petit à petit, c''est votre réalité qui change. L''image que vous projetez sur l''écran se transforme: les pleurs font place aux rires et votre paix intérieure augmente. Vous sentez votre coeur se dilater et vous commencez à comprendre en quoi consiste le bonheur.

This volume LNCS 16229 constitutes the refereed proceedings of 26th International Conference on Formal Methods and Software Engineering, ICFEM 2025, in Hangzhou, China, during November 10–13, 2025.The 20 full papers presented were carefully reviewed and selected from 47 submissions.
