摘要： A method for calibrating a delay element is described herein. In some embodiments, the method may include generating a clock signal with a clock edge, generating a reference signal with a reference edge using an adjustable delay line to delay the clock signal, and delaying a selected one of the clock signal and the reference signal through an array delay line having an array delay element with an array delay. In some embodiments, the method may further include adjusting the adjustable delay line to obtain a first adjustable delay so that the clock and reference edges are aligned on one side of the array delay element, adjusting the adjustable delay line to obtain a second adjustable delay so that the clock and reference edges are aligned on the other side of the array delay element, and ascertaining a delay difference between the first and the second adjustable delays to determine a value of the array delay provided by the array delay element. Other embodiments of the present invention may include, but are not limited to, apparatuses and systems adapted to facilitate practice of the above-described method.

摘要： Some implementations disclosed herein provide techniques and arrangements for transferring data between asynchronous clock domains. A synchronization signal may be generated by a first of the clock domains, and data may be transferred between the domains in response to the synchronization signal. Clock cycles of the second of the clock domains may be monitored in comparison to the synchronization signal to report the number of second clock domain cycles occurring per occurrence of the synchronization signal. This information may be recorded by testing and validation equipment to facilitate error analyses.

摘要： A system and method for processing signals determines rise and fall times of a driving signal, compares the rise and fall times to desired values, and independently controls the rise and fall times to equal the desired values. The rise and fall times may be controlled by generating one or more first correction bits based on a difference between the rise time and a corresponding one of the desired values, generating one or more second correction bits based on a difference between the fall time and a corresponding one of the desired values, and then separately applying the bits to independently control the rise and fall times of the driving signal. The driving signal may be an I/O signal or another type of signal.
