摘要： A scheme for noise floor de-embedding by identifying a link or relationship between noise floor from an oscilloscope and phase jitter impact on a toggling signal. The scheme uses phase or electrical spectrum and phase detection for noise floor recognition. The scheme de-embeds the impact from random noise and also removes deterministic noise or jitter from the oscilloscope. The scheme provides accurate jitter analysis for a circuit (e.g., clock data recovery circuit) after de-embedding noise floor for the oscilloscope.

摘要： Briefly, system and method for message-based power management which may be used, for example, in computer systems and communications networks. Embodiments of the present invention may include, for example, a device connected to a power management controller (PMC); the device and/or the PMC may send, receive, and/or process power management event (PME) messages. Embodiments of the present invention may operate using links in communicative and/or non-communicative modes. Embodiments of the present invention may include a switch, to send/receive, process, create, re-format and/or route one or more PME message on behalf of various devices, for example, a Peripheral Component Interconnect (PCI) device.

摘要： According to one embodiment, a built-in self test (IBIST) architecture/methodology is disclosed. The IBIST provides for testing the functionality of an interconnect (such as a bus) between a transmitter and a receiver component. The IBIST architecture includes a pattern generator and a pattern checker. The pattern checker operates to compare a received plurality of bits (for the pattern generator) with a previously stored plurality of bits.
