    摘要: A proactive noise suppression system and method for a power supply network of an integrated circuit. The system and method include receiving an IC event sequence to a memory element, correlating the IC event sequence to a storage location in a second memory element, the storage location including an anti-noise response signature, and utilizing the anti-noise response signature to proactively generate an anti-noise response in a power supply network in at least a portion of the integrated circuit at about the time of execution of the first IC event sequence. Anti-noise response signatures may be adaptively updated and/or created based on noise measurements made corresponding to execution of an IC event sequence by the integrated circuit.

    摘要: Design structures, method and systems of powering on an integrated circuit (IC) are disclosed. In one embodiment, the system includes a region in the IC including functional logic, a temperature sensor for sensing a temperature in the region when the IC is powered up and a heating element therefor; a processing unit including: a comparator for comparing the temperature against a predetermined temperature value, a controller, which in the case that the temperature is below the predetermined temperature value, delays functional operation of the IC and controls heating of the region of the IC, and a monitor for monitoring the temperature in the region; and wherein the controller, in the case that the temperature rises above the predetermined temperature value, ceases the heating and initiates functional operation of the IC.

    摘要: A method and system for reducing clock noises are disclosed. A clock signal includes active edges and inactive edges. Inactive edges produce clock noise but are not critical to the functionality of the clock signal. That is, only active edges are critical to proper timing of an integrated circuit (IC). As such, inactive edges of clock signals to clocked elements of an IC may be shifted to be misaligned to one another. As a consequence, peak noise produced by the inactive edges will be spread over a large area and therefore will be reduced in amplitude.
