Abstract: Described herein is the method and apparatus for determining frequency of an oscillator coupled with one or more analog devices, and for determining within-die or across-die variations in an analog property associated with the one or more analog devices, the determining based on the oscillator frequency. The analog property includes output signal swing, bandwidth, offset, gain, and delay line linearity and range. The one or more analog devices include input-output (I/O) buffer, analog amplifier, and delay line. The method further comprises updating a simulation model file based on the determining of the within-die and/or across-die variations of the analog property.

Abstract: A plurality of fuse cells are arranged in an array. One or more fuse cells include a pair of fuse devices to output a pair of voltages, respectively, wherein the pair of fuse devices are redundantly programmed. A sense amplifier is coupled to the plurality of fuse cells to read the pair of voltage outputs from each of the plurality of fuse cells, respectively. A comparator circuit is coupled to the sense amplifier to compare the pair of voltage outputs for each of the plurality of fuse cells and to output the compared result.

Abstract: A method and device may determine the absence of a periodic signal or the absence of an edge of the periodic signal. The periodic signal may be a transmitted clock signal in a forwarded clock architecture. The periodic signal may be delayed by a fixed phase difference to produce a delayed periodic signal. The phase difference between the periodic signal and the delayed periodic signal may be determined. If the determined phase difference is above or below the fixed phase difference by a predetermined amount or more the periodic signal may be missing an edge. If the absence of the periodic signal or the absence of the edge of the periodic signal is detected, an error signal may be asserted. The error signal may be an in-band reset signal.
