Abstract
A power converter circuit included in a computer system may include a phase circuit and a sample circuit. The phase circuit compares a voltage level of the regulated power supply node to a reference voltage to generate a demand current that is used to adjust the voltage level of the regulated power supply node. The phase circuit also digitizes the demand current and stores the resultant bit stream in a memory circuit. The sample circuit generates timestamp information that points to particular storage locations in the memory circuit that correspond to trigger events, allowing the operation of the power converter circuit to be analyzed during different circumstances as well as to adjust operating parameters of the power converter circuit.
