Description

A fully digital system to detect and correct setup/hold time violations in digital circuits, is presented. The proposed system benefits from simple, low-power, small-area, and easy-to-modify design. The system is composed of two separate blocks, detector and corrector connected through a 2-bit control signal. The detector is placed near flip-flops or memory elements and sends control signals to the corrector. Corrector circuitry consists of only CMOS inverters and a multiplexer, either after global clock source to correct clock globally or before the elements to correct them locally.
