2.2.4 Correlation Data

All the CSV files, including bench test, Simplis simulation and Cadence simulation results of CSV files, can be copied into one excel file to do correlation. Figure 2-11 is the load transient correlation waveform. Based on this waveform, tuning parameters would be effective based on overshoot, undershoot, response time differences. This application note would not describe how to tune loop parameters to make results match.
