Abstract

This paper describes a set of tools for the reengineering of computer-based systems, in particular software. The toolset is based on an abstract intermediate representation (IR) which incorporates the system software architecture at five levels of granularity: program level, task level, package/ object instance level, subprogram level and statement level. The toolset provides a graphical user interface that allows various views of a software architecture, including call graph, rendezvous graph, call-rendezvous graph, call-data-rendezvous graph, control flow graph and dependence graphs. The information captured by the toolset is useful in software structure, flow and interaction analysis, tasks commonly performed manually during maintenance and reengineering. This information is also helpful for understanding the software design to guide software transformation, and for porting software to distributed platforms.
