This volume contains the papers presented at the 7th International Symposium on Automated Technologyfor Veri?cation and Analysis held during October 13- 16 in Macao SAR, China. The primary objective of the ATVA conferences - mains the same: to exchangeand promote the latest advances of state-of-the-art researchon theoretical and practical aspects of automated analysis, veri?cation, and synthesis. Among 74 research papers and 10 tool papers submitted to ATVA 2009, the Program Committee accepted 23 as regular papers and 3 as tool papers. In all, 33 experts from 17 countries worked hard to make sure that every submission received a rigorous and fair evaluation. In addition, the program included three excellenttutorialsandkeynotetalksbyMarkGreenstreet(U.BritishColumbia), Orna Grumberg (Technion), and Bill Roscoe (Oxford University). The conf- ence organizers were truly grateful to have such distinguished researchers as keynote speakers. Many worked hard and o?ered their valuable time so generously to make ATVA 2009 successful. First of all, the conference organizers thank all 229 - searchers who worked hard to complete and submit papers to the conference.

Many organizations sponsored the symposium. They include: The United Nations University, International Institute of Software Technology (UNU-IIST); Macao Polytechnic Institute (MPI); Macao POST;and FormalMethods Europe (FME). The conference organizers thank them for their generous support and assistance.
This book constitutes the proceedings of the 7th International Symposium on Automated Technology for Verification and Analysis, ATVA 2009, held in Macao, China, in October 2009.
The 23 regular papers and 3 took papers presented together with 3 invited talks, were carefully reviewed and selected from 74 research papers and 10 tool papers submissions.
The papers are organized in topical sections on state space reduction, tools, probabilistic systems, medley, temporal logic, abstraction and refinement, and fault tolerant systems.
