Patent ID: 8106705

Claim:
An electronic circuit comprising: (A) a plurality of regions; and (B) a reference module for generating a reference signal having a value which is substantially independent of PVT conditions local to the plurality of regions, wherein each respective region in the plurality of regions is supplied by a corresponding mutually different supply voltage and wherein each respective region in the plurality of regions comprises: (i) a corresponding functional module; (ii) a corresponding condition signaling module for generating a corresponding indication signal indicative for PVT conditions local to the corresponding functional module, said PVT conditions comprising a set of conditions relevant for the corresponding functional module comprising at least one of said corresponding mutually different supply voltage supplied to said corresponding functional module, a temperature within a corresponding area occupied by said corresponding functional module and the process conditions relevant for said corresponding area; and (iii) a corresponding control circuit for comparing the corresponding indication signal and the reference signal, and for generating a corresponding control signal for the corresponding functional module.
