摘要:
A method and system for monitoring and compensating the performance of an operational circuit is provided. The system includes one or more integrated circuit chips and a controller. Each integrated circuit chip includes one or more operational circuits, each operational circuit having at least one controllable circuit parameter. Each integrated circuit chip also includes a process monitor module at least partially constructed thereon. The controller is coupled to each process monitor module and to each operational circuit. The controller includes logic for evaluating the performance of an operational circuit based on data obtained from process monitor module and operational circuit related data stored in a memory. Based on the evaluation, the controller determines whether any deviations from desired or optimal performance of the circuit exist. If deviations exist, the controller generates a control signal to initiate adjustments to the operational circuit to compensate for the deviations.
