Patents by Inventor GARY L. PHIFER

GARY L. PHIFER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10061883
    Abstract: One embodiment of the invention includes a method for generating a Reciprocal Quantum Logic (RQL) circuit design via a synthesis tool. The method includes providing data associated with behavior and constraints of the RQL circuit design and a component library to the synthesis tool. The method also includes generating an RQL netlist circuit comprising a flip-flop device placeholder and a circuit system coupled to at least one of an input and an output of the flip-flop device placeholder via the synthesis tool based on the data and a component library. The method also includes separating the circuit system into circuit subsystems that are each associated with a separate respective phase of a clock signal via the synthesis tool based on inputs. The method further includes removing the flip-flop device placeholder from the RQL netlist circuit via the synthesis tool to generate the RQL circuit design from the RQL netlist circuit.
