This volume contains the papers presented at SBMF 2009: the Brazilian S- posium on Formal Methods, held during August 19-21, 2009 in Gramado, Rio Grande do Sul, Brazil. The SBMF programme included three invited talks given by Leonardo de Moura (Microsoft Research), Sebastian Uchitel (University of Buenos Aires and Imperial College London), and Daniel Kro ¨ning (University of Oxford). The symposium was accompanied by two short courses: - Introduction to Software Testing, given by Marci ´ o Eduardo Delamaro (U- versity of Sao ˜ Paulo) - Formal Models for Automatic Test Case Generation, given by Patr´ ?cia Machado and Wilkerson Andrade (Federal University of Campina Grande) This year, the SBMF symposium had a special section on the Grand Ch- lenge in Veri?ed Software, inspired by recent advances in theory and tool s- port. WorkonthegrandchallengestartedwiththecreationofaVeri?edSoftware Repository with two principal aims: - To collect a set of veri?ed software components - To conduct a series of industrial-scale veri?cation experiments with theor- ical signi?cance and impact on tool-support This special session on the grand challenge was dedicated to two pilot projects currently underway: - The Flash File Store. The challenge is to verify the correctness of a fau- tolerant,POSIX-compliant?lestoreimplemented on?ashmemory. Veri?- tion issues include dependability guarantees as well as software correctness. Levels of abstractioninclude requirements speci?cation, software design, - ecutable code, device drivers,and ?ash translationlayers. The challenge was inspired by the requirements for forthcoming NASA space missions. - FreeRTOS.
