  • Patent number: 11900264
    Abstract: Hybrid quantum-classical approaches for solving computational problems in which results from a quantum processor are combined with an exact method executed on a classical processor are described. Quantum processors can generate candidate solutions to a combinatorial optimization problem, but since quantum processors can be probabilistic, they are unable to certify that a solution is an optimal solution. A hybrid quantum-classical exact solver addresses this problem by combining outputs from a quantum annealing processor with a classical exact algorithm that is modified to exploit properties of the quantum computation. The exact method executed on a classical processor can be a Branch and Bound algorithm. A Branch and Bound algorithm can be modified to exploit properties of quantum computation including a) the sampling of multiple low-energy solutions by a quantum processor, and b) the embedding of solutions in a regular structure such as a native hardware graph of a quantum processor.

  • Patent number: 11868695
    Abstract: Aspects of the present disclosure address systems and methods for driver resizing using a transition-based capacitance increase margin. An integrated circuit (IC) design stored in a database in memory is accessed. The IC design comprises a net comprising a set of driver cells. A capacitance increase margin for resizing an initial driver cell is determined based on a total capacitance of the net and transition time target associated with the initial driver cell. An alternative driver cell is selected from a library to resize the initial driver cell and is used to replace the initial driver cell in the net. The alternative driver is selected such that a pin capacitance of the alternative driver cell exceeds an initial pin capacitance corresponding to the initial driver cell by no more than the capacitance increase margin.
