Latest Patents
Ghun Kim's latest patents include a "Method and apparatus for grouping flip-flops by timing." This invention provides a system that facilitates the placement of flip-flops in an integrated circuit based on timing requirements. The system operates by first receiving a netlist for flip-flop connectivity. It then determines a metal layer class definition for each signal in the netlist based on the timing requirements of the corresponding flip-flop. The system classifies a flip-flop instance using this definition and associates it with a group of other flip-flops that share the same metal layer class definition. Finally, it determines a position for the group by replacing an existing repeater in the integrated circuit with the group of flip-flops.
Another significant patent is the "Method and apparatus for analyzing inductive effects in a circuit layout." This invention considers inductive effects while analyzing noise and propagation delay in a circuit layout. The system first receives the circuit layout, which specifies a plurality of nets carrying signals between circuit elements. It converts a given net into a single signal path divided into segments, calculating inductance, capacitance, and resistance values for each segment. The system then produces a model for each segment and couples these models into a comprehensive model for the given net, ultimately determining the noise and propagation delay effects.
