Information modelling of folded and unfolded design

An information model for a folded design description which corresponds to electronic design interchange format (EDIF) version 2.0.0, using the language Express, is presented. It is shown that it can be easily extended to a model for an unfolded description. A method to compute the actual values for occurrences of views, nets, and ports, is given, which is based on the back-annotation facilities of EDIF and may help to uncover EDIF's underlying semantics.<
