Abstract:
1. A method, comprising: determining characteristics of an integrated circuit (IC); determining a module specific voltage of the IC to meet a designed target frequency and power characteristics, based on the determined IC characteristics; setting the module specific voltage by using a combination of fuses within the IC; setting a clock frequency which is lower than an operating frequency of the IC; applying a default voltage driven from an external control; driving the default voltage at output pins of the IC; increasing the clock frequency to a nominal operating frequency of the IC; discontinuing the external control so that the default voltage specified by the IC now controls a voltage regulator module (VRM); reading the fuses to determine the appropriate voltage adjustment for driving the IC under certain power and specification conditions; and adjusting the IC to the module specific voltage corresponding to the fuse values used to drive the output pins.
