AUTO-COMPENSATION SELECTION FOR
DIGITAL VOLTAGE REGULATOR CONTROLLERS
 This disclosure generally relates to voltage regulators.
 Voltage regulator controllers may be used in circuits to regulate voltage levels for the circuit. For example, a portion of a circuit that requires a particular voltage level may include a voltage regulator that outputs a voltage level of that particular voltage level to the portion of the circuit. The voltage regulator controller may include various components, e.g., resistors and capacitors, that have resistive or capacitive values based on performance criteria for the voltage regulator. For example, voltage regulator controllers that are designed to compensate for the same input voltage load current variations but designed to provide different output voltage levels may include the same circuit diagrams but different values for corresponding resistors and capacitors.
 In general, an aspect of the subject matter described may involve a process for selecting settings for a digital voltage regulator controller. A digital voltage regulator controller may include electrical components, e.g., resistors, capacitors, etc., that may have settings, e.g., resistive, capacitive, etc., values, that may be digitally set to a finite set of values based on desired performance of the digital voltage regulator controller. Accordingly, to determine the set of settings to use for a digital voltage regulator controller with a particular circuit diagram, a process may include generating the sets of all possible settings for the circuit diagram, calculating the performance for each setting, and selecting a particular set of settings based on the performance.

 FIG. 1 is an example circuit 100 including a digital voltage regulator controller. The digital voltage regulator controller includes three capacitors, C1 (110), C2 (112), and C3 (114), and three resistors, R1 (120), R2 (122), and R3 (124). The capacitive values and the resistive values for the capacitors and the resistors may be digitally set. For example, each capacitor and resistor may be associated with a 4-bit register and may be set to one of sixteen values corresponding to the value stored by the 4-bit register, where the capacitive and resistive values correspond to the stored values.
 A particular set of values for the components of the digital voltage regulator controller may be a set of settings for the digital voltage regulator controller. For example, a particular set of settings may be 10k ohms for R1, 150k ohms for R2, 2.49k ohms...
