Zusammenfassung:A method and apparatus for delay tuning an integrated circuit which includes a delay element that includes a plurality of delay stages interconnected in a cascaded relationship, each stage imposing an incremental delay upon the input signal when enabled, the delay element receives a selection signal that determines how many of the delay stages are enabled. By varying the select signal, the delay element imposes a variable delay upon the input signal for testing and evaluation.
