This invention provides a graphical tool by which a person may quickly and
efficiently check the relational information between elements of a
computer model. The invention may be used to quickly validate the design
rules, like minimum spacing requirements between the connections (or
nets) in a schematic that exists in a computer aided design package.
Since a designer must enter such design rules for each net, the invention
first imports these design rules from the computer model and then imports
a standard set of design rules. After comparing both the sets of design
rules, the invention presents a graphical display (a matrix) to a user
indicating where the model rules matched the standard set and,
correspondingly, where they did not match.
