摘要： A variable digital delay line with an insertion delay as low as a single delay element yet capable of providing a large programmable delay with a small simple control mechanism. A loop connects an input to an output through selectable first delay elements such as 2:1 muxes and selectable second delay elements such as pairs of inverters by way of a plurality of intermediate nodes having a tap. A plurality of sneak paths are available wherein the loop by passes a remainder of first delay elements and/or second delay elements by way of the taps at the intermediate nodes.

摘要： A glitch free delay line multiplexing technique is described that includes an intermediate multiplexing system and an output multiplexer. The intermediate multiplexing system receives signals from a plurality of delay units and outputs a subset of delay signals that includes the signal presently selected, the signal presently selected with an additional delay, and the signal presently selected with one less delay. The intermediate multiplexing system receives a control word from a select mechanism in a non-time critical manner. The output multiplexer receives the least significant bits of the control word and outputs the selected signal.

摘要： On-chip sensor to detect power supply vulnerabilities. The on-chip sensor employs a sensitive delay chain and an insensitive delay chain to detect power supply undershoots and overshoots without requiring external off-chip components. Undershoots and overshoots outside a user-defined threshold are detected. The undershoots and overshoots are indicated by a relative difference in phase of the two delay chains. The two delay chains are programmable to detect various frequencies.

摘要： A mechanism for de-skewing and aligning data bits sent between two chips on an elastic interface. On the receiving end of an elastic interface, the eye of each data bit within a clock/data group is delayed by less than a bit time to align the eyes with the nearest clock edge of a received clock signal. In addition to aligning the eyes of the individual data bits with the nearest clock edge, IAP patterns are used to determine the amount of further delay needed to line up the individual data beats from each data bit. If the data beats for the data bits are not aligned, all but the slowest data beat are delayed to align the data beats for all bits. The additional delay is achieved using sample latches that result in a delayed signal with less jitter. As a result of having less jitter, the received, de-skewed, and aligned clock/data group can be forwarded to the operative portion of the receiving chip at an increased frequency.
