Physics and detector simulations

The simulation tools session was divided into three main areas of concentration: physics event simulation and event generators, full detector simulation and event reconstruction frameworks, and fast simulation and physics analysis frameworks. Although the primary purpose of the plenary session talk was to summarize the contents of the parallel session presentations for those unable to attend, the intent of this write-up is to attempt to point out features in common among the ongoing efforts and present a personal view of some goals for the future. The reader is directed to the individual write-ups for details on the specific topics discussed during the workshop. A brief summary and synthesis of topics presented during the tools parallel sessions.
