ON-CHIP VOLTAGE PREDICTION CIRCUIT BASED ON PARAMETERS OF POWER DELIVERY NETWORK

The provided is an on-chip voltage prediction circuit based on parameters of the chip's power delivery network. The circuit includes: an on-chip PDN impedance scanning module, an on-chip voltage monitoring module, an on-chip PDN parameter lookup table storage module, an on-chip predictive digital power meter, and an on-chip voltage prediction-calculation module. The circuit establishes a physical model that maps historical voltages and predicted current information to predicted voltage information. By quantizing the model and using the voltage monitoring circuit and the predictive digital power meter together, the provided implements on-chip deployment of the voltage prediction circuit, and effectively predicts future on-chip voltages.
