Disclosed are methods, systems, and articles of manufacture for implementing a schematic circuit design component as a transmission line model in a schematic driven extracted view for an electronic design. These techniques identify a schematic circuit component design form a schematic design of an electronic design and identify or determine layout device information of a layout circuit component design corresponding to the schematic circuit component design. An extracted view may be generated or identified for the electronic design at least by using a transmission line model based in part or in whole upon connectivity information or a hierarchical structure of the electronic design. The electronic design may then be modified or updated based in part or in whole upon results of performing one or more analyses on the extracted view with the transmission line model.

Disclosed are techniques for implementing a layout-driven, multi-fabric schematic design of an electronic design. These techniques identify a multi-fabric layout spanning across multiple design fabrics and layout connectivity information and determine a device map that correlates a first set of devices in the multi-fabric layout with respective parasitic models. The device map can be identified one or more pre-existing device maps or can be constructed anew. A multi-fabric schematic can be generated by using at least the respective parasitic models and the layout connectivity information.

A design system provides data structures to store parameters of physical structures that can be viewed and modified through a graphical design interface. Certain of the structures of the physical system may be partitioned into a subsystem such that the data describing the subsystem includes physical topology data defining relative locations of the structures in the physical system. The physical topology data is back-annotated into a logical topology, such as in accordance with a predefined logical topology template. The logical data abstraction of the circuit design is kept synchronized with the physical data and presented in a logical topology that is kept legible through the prudent selection of logical topologies representing the physical subsystem design.

Physical topology-driven logical design flow

A design system provides data structures to store parameters of physical structures that can be viewed and modified in a front-end process through a logical design interface. In this way, system behavior defined by component structure can be evaluated and modified through a schematic representation of the data, regardless of a state of data representing the physical layout of interconnected physical structures. In electric circuit applications, for example, high frequency circuits can be incrementally designed and evaluated through structural parameters defined in a schematic diagram data abstraction without modifying and evaluating a layout data abstraction of the circuit directly.
