Abstract
An asymmetrical aging control system is described. This system actively varies associated dedicated circuits in a manner that minimizes power consumption, while preventing asymmetrical aging.
Claims12
Asymmetrical aging control system associated with a dedicated circuit, comprising:
- a first selection device adapted to be coupled to an input of the dedicated circuit;
- a second selection device adapted to be coupled to a mode changing control input of the dedicated circuit;
- a third selection device adapted to coupled to a clock input of the dedicated circuit;
- control logic for receiving an input signal, transmitting a scan data signal to the first selection device, and transmitting mode control signal to the second selection device;
- a register for transmitting random data for the second selection device;
- and
- a counter for transmitting a first count signal to the second selection device and the register, and for transmitting a second count signal to the third selection device,
- wherein the asymmetrical control logic uses a scan path associated with the dedicated circuit for varying data on at least one of the inputs of the dedicated circuit in a manner that minimizes power consumption of the associated dedicated circuit when the associated dedicated circuit is inactive.

A computer readable medium with logical functions for controlling asymmetric aging of dedicated, comprising the steps consisting of:
- enabling asymmetric aging control on all of the dedicated circuits;
- disabling asymmetric aging control on active dedicated circuits;
- monitoring a state associated with each dedicated circuit;
- disabling asymmetric aging control for a first dedicated circuit associated with an activate request;
- and
- deactivating a second dedicated circuit associated with a deactivate request.

A router having a plurality of slots for expanded capacity, comprising:
- an ASIC for facilitating data transmission to each of the slots and comprising a plurality of dedicated circuits associated with the slots;
- and
- asymmetrical aging control circuit for either enabling or disabling a plurality of asymmetrical aging control logic, and each asymmetrical aging control logic is associated with each of the dedicated circuits,
- wherein each of the asymmetrical aging control logic uses a scan path associated with the ASIC for varying data on its inputs in a manner that minimizes power consumption of the associated dedicated circuit while the associated dedicated circuit is inactive.
