Latest Patents

One of his latest patents is the "Nonlinear driver model for multi-driver systems." This innovation involves a precharacterized cell library for EDA tools that includes driver model data, which consists of output current signals indexed by output voltages. The driver model can generate an output by interpolating these output current signals using the output voltage, allowing for the generation of updated output voltage across predetermined time increments. This process can be repeated to create model output current and voltage signals that closely match the actual signals from a driver in a multi-driver system.

Another notable patent is the "Non-linear receiver model for gate-level delay calculation." This characterized cell library for EDA tools includes receiver model data that provides multiple capacitance values for various modeling situations. By utilizing different capacitance values, the receiver model can generate portions of the model receiver signal, enabling more accurate matching of actual receiver signal timing characteristics. This two-capacitance receiver model enhances accuracy without significantly increasing cell library size or computational complexity.
