摘要:
Disclosed encompasses method, system, computer program product for implementing interactive checking of constraints. Various embodiments bridge schematic design environment and layout environment with a binder mapping process and utilize connectivity information from the schematic design to identify constraint violations early in the physical design stage. The method identifies or creates a layout and identifies or generates an object for a modification process. The method may take snapshot(s) of the design database or may use one or more logs for restoring the design database. The method then identifies or creates scratch pad(s) and performs modification process on the object to generate a change. The method uses scratch pad(s) and trigger(s) to perform constraint checking during the modification process to provide interactive feedback in response to the modification process before committing the change to the persistent database.
摘要:
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.
