Latest Patents

One of his latest patents is titled "Propagating physical design information through logical design hierarchy of an electronic circuit." This innovative system determines physical design information along a logic hierarchy of a circuit design. It accesses physical design metrics associated with different parts of a physical design of a circuit. The system also accesses a logic design of the circuit comprising a hierarchy of logic blocks. It determines the physical design metrics associated with one or more logic blocks of the hierarchy based on the relation between the physical design and the logic design. Furthermore, the system configures a user interface to display the hierarchy of the logic design of the circuit along with the physical design metrics associated with the one or more logic blocks of the hierarchy. Finally, the system sends the configured user interface for display.

Another notable patent is the "Fast topology bus router for interconnect planning." This method includes receiving a netlist for a chip that includes a bus and determining, by one or more processors and based on the netlist, a first routing topology for the bus through a routing region of the chip. This is achieved by comparing the demand of the bus to the capacity of a plurality of cells of the routing region. The method also includes generating a layout for the chip based on the first routing topology.
