1. System comprising a microelectronic circuit and a controllable voltage source with an output coupled to said microelectronic circuit for providing an operating voltage to said microelectronic circuit, wherein:
said microelectronic circuit is an adaptive microelectronic circuit, performance of which is at least partly configurable by selecting a value of said operating voltage at said output,
said system is configured to regulate said operating voltage at said output into conformity with a target value, so that re-regulating said operating voltage into conformity with a new, changed target value involves a time constant,
said microelectronic circuit comprises a first processing path, on which a first register circuit comprises a data input coupled to an output of a first logic unit that precedes said first register circuit on said first processing path,
said microelectronic circuit is configured to respond to a digital value at said data input changing later than an allowable time limit by generating a timing event observation signal, hereinafter TEO signal, wherein said allowable time limit is defined by at least one triggering edge of at least one triggering signal coupled to said first register circuit,
said system is configured to use said TEO signal to trigger an increase in said operating voltage at said output faster than said time constant.
