Abstract
Memory performance in programmable logic is significantly increased by adjusting circuitry operation to adjust for variations in process, voltage, or temperature. A calibration circuit adjusts control signal timing, dynamically and automatically, to compensate real time to process, voltage, and temperature variation. A feedback system using a control block and a dummy mimicking concept are provided.
