Abstract
A method for estimating accuracy of an on-chip temperature sensor is provided. A representative power supply waveform having noise is input into a simulation of the on-chip temperature sensor and the accuracy of the on-chip temperature sensor is estimated from the simulation. A computer system for estimating accuracy of an on-chip temperature sensor is also provided. A computer-readable medium having instructions adapted to input a representative power supply waveform having noise into a simulation of an on-chip temperature sensor and estimate accuracy of the on-chip temperature sensor from the simulation is provided.
