Vectorless Prediction of Simultaneous Switching Noise from FPGAS


Switching of logic gates in integrated circuits is responsible for significant power supply noise on the chip and on the printed circuit board (PCB). Predicting power supply noise can be critical for analyzing the proper operation of high-speed devices. A vectorless method was developed to predict the statistical distribution of dynamic currents drawn by an IC and was used to predict the statistical characteristics of power supply noise on the PCB. Simulations and measurements of noise on the PCB power delivery network demonstrate the approach can determine the average and standard deviation of the power supply voltage within 20%, which is more than sufficient for predicting the statistical impact of switching noise on circuit performance.
