RESUMO

Digital system design has reached a high degree of complexity that prevents its realization without CAD tools. The starting point of such tools consists on a conceptual view of the intended system (given by one or more conceptual models), which is captured for computational handling by one or more specification languages. Several of such languages were developed aiming to capture as many hardware and software characteristics as possible, according to different design methodologies. Petri net is a class of conceptual models for parallel system modeling. Some Petri net extensions have been proposed aiming at describing digital systems characteristics as accurately as possible. However, only two of them have nearly all features needed to describe such systems in full. This work presents a Petri net extension developed to overcome the restrictions for digital system modeling through Petri net extensions. A hardware/software codesign methodology in which the proposed extension can be used as the internal modeling language is presented as well. Such a framework aims embedded digital system description, simulation, analysis, validation, and high-level synthesis.
