Abstract: A method and circuitry that enables an input/output pin (I/O) on a System on a Chip to function either as an analog or as a digital input/output without compromising the overall performance of the system, thus giving the automated test equipment full flexibility to maximize parallel testing for both analog and digital modules.

Abstract: The optimal operating voltage of a complex SoC may be influenced by process variations. The operating voltages may be dynamically adjusted for optimal performance. These adjustments require a dynamic reconfiguration of the voltage monitoring thresholds in the power on reset circuitry of the SoC.
