In order to increase productivity, methodologies based on reuse of previously designed components are exploited by the Integrated Circuit (IC) design community. However, designers are often faced with the problem of reusing a legacy design for which the behavior is unclear due to missing documentation and the complexity of the design. In this dissertation a methodology to assist designers in retrieving the original intent of a design from its Hardware Description Language (HDL) specification is described. The methodology is based on code analysis and techniques which produce different views of HDL code. These views represent the behavior of a design in more abstract terms than the HDL code. / Graduate
