ABSTRACT:
A programmable logic device may comprise a metric circuit operable to repeatedly perform a function and emit a first signal dependent upon its advancement into the function. A comparator may compare the first signal from the metric circuit to a predetermined reference signal. A controller may then selectively disable a portion of the programmable logic device dependent upon the results of the comparison. In a particular case, the weakened circuit may be a counter that repeatedly advances its count with a rate dependent upon an aging characteristic of a vulnerable element.
