摘要： Operating speeds of integrated circuit devices are tested to establish maximum and minimum frequency at maximum and minimum voltage. The devices are sorted into relatively-slow and relatively-fast devices to classify the devices into different voltage bins. A bin-specific voltage limit is established for each of the voltage bins needed for core performance at system use conditions. The bin-specific voltage limit is compared to core minimum chip-level functionality voltage at system maximum and minimum frequency specifications. The method correlates system design evaluation of design maximum and minimum frequency at design maximum and minimum voltage conditions with evaluation of tested maximum and minimum frequency at tested maximum and minimum voltage conditions. A chip-specific functionality voltage limit is established for the device. Initial system voltage for all devices from a voltage bin is set at a greater of the bin-specific voltage limit and the chip-specific functionality voltage limit consistent with the evaluation conditions.

摘要： Circuits and methods are provided for a reliability, availability and serviceability (RAS) enabled and self-regulated frequency and delay sensor of a semiconductor. A circuit for measuring and compensating for time-dependent performance degradation of an integrated circuit, includes at least one critical functional path of the integrated circuit, and Wearout Isolation Registers (WIR's) connected to boundaries of the critical functional path. The circuit also includes a feedback path connected to the WIR's, and a sensor control module operable to disconnect the critical functional path from preceding and succeeding functional paths of the integrated circuit, connect the critical functional path to the feedback path to form a critical path ring oscillator (CPRO), and enable the CPRO to generate an operating signal. A delay sensor module is operable to measure a frequency of the operating signal to determine and compensate for a degradation of application performance over a lifetime of a semiconductor product.
