Parametric Data-Based Process Monitoring for Adaptive Body Bias Control

摘要

Various embodiments of systems and methods are disclosed for providing adaptive body bias control. One embodiment comprises a method for adaptive body bias control. One such method comprises: modeling parametric data associated with a chip design; modeling critical path data associated with the chip design; providing a chip according to the chip design; storing the parametric data and the critical path data in a memory on the chip; reading data from a parametric sensor on the chip; based on the data from the parametric sensor and the stored critical path and parametric data, determining an optimized bulk node voltage for reducing power consumption of the chip without causing a timing failure; and adjusting the bulk node voltage according to the optimized bulk node voltage.
