1. A method comprising:
performing a plurality of monitoring operations on a system on chip (SoC) at a respective first plurality of voltage values;
causing error rate data gathered from each of the plurality of monitoring operations to be entered into a database, wherein the entered error rate data is associated with the first plurality of voltage values;
generating a first portion of a plot using the gathered error rate data in the database and a second portion of the plot at a respective second plurality of voltage values at which the plurality of monitoring operations are not performed, wherein the second portion of the plot is generated using estimated error rate data by extrapolation from the first portion of the plot; and
responsive to determining a particular voltage value greater than each of the first plurality of voltage values based on the first portion and second portion of the plot and a particular error rate associated with the particular voltage value:
performing one or more operations on the SoC using the determined particular voltage; and
monitoring a temperature of the SoC and correlating the temperature to the particular voltage value.
