Recognizing and utilizing circuit topology in an electronic circuit design

Abstract

This application discloses tools to build a topology library including one or more topologies, each of which includes a description of multiple transistors, their parameters, and associated connectivity, and also includes rules or criteria to be utilized in downstream design flow processes. The tools can analyze a circuit design describing an electronic device to recognize a subset of transistors in the electronic device has a pre-defined circuit topology, and identify layout rules or simulation criteria for the transistors in the recognized circuit topology. The tools can utilize the layout rules to automatically generate a portion of a physical design layout corresponding to the recognized topology in the circuit design. The tools also can compare results from a simulation of the circuit design that correspond to the transistors in the recognized circuit topology to the simulation criteria to determine whether the transistors in the recognized circuit topology meet design specifications.
