Disclosed are methods and systems for implementing constraint and connectivity aware physical designs. The method or system provides a connectivity-aware environment to implement electronic designs. For example, the method interactively determines whether an electronic design complies with various constraints by using connectivity information in a nearly real-time manner while the electronic design is being created in some embodiments. The method or system uses the connectivity information provided by a connectivity engine or specified by designers to present feedback to a user as to whether a newly created object or a newly modified object complies or violates certain relevant constraints in an interactive manner or in nearly real-time without having to perform such constraints checking in batch mode. The method further enables one to implement electronic designs by using connectivity information without performing extraction on layouts or rebuilding nets.
