摘要： A system, apparatus, and method for analyzing photon emission data to discriminate between photons emitted by transistors and photons emitted by background sources. The analysis involves spatial and/or temporal correlation of photon emissions. After correlation, the analysis may further involve obtaining a likelihood that the correlated photons were emitted by a transistor. After correlation, the analysis may also further involve assigning a weight to individual photon emissions as a function of the correlation. The weight, in some instances, reflecting a likelihood that the photons were emitted by a transistor. The analysis may further involve automatically identifying transistors in a photon emission image.

摘要： An apparatus and method for laser probing of a DUT at very high temporal resolution is disclosed. The system includes a CW laser source, a beam optics designed to point two orthogonally polarized beams at the same location on the DUT, optical detectors for detecting the reflected beams, collection electronics, and an oscilloscope. The beam optics defines a common-path polarization differential probing (PDP) optics. The common-path PDP optics divides the laser beam into two beams of orthogonal polarization. Due to the intrinsic asymmetry of a CMOS transistor, the interaction of the beams with the DUT result in different phase modulation in each beam. This difference can be investigated to study the response of the DUT to the stimulus signal.

摘要： Systems, methods, and other embodiments associated with auto-negotiating over a single pair PHY are described. According to one embodiment, an apparatus includes a physical layer (PHY) transceiver configured to communicate over a single twisted pair channel. The apparatus includes a setup logic configured to control the PHY transceiver to initiate an auto-negotiation sequence over the single twisted pair channel with a remote device upon detecting a transmission from the remote device on the single twisted pair channel. The auto-negotiation sequence includes an exchange of parameters with the remote device using a half-duplex mode to communicate on the single twisted pair channel.

摘要： A medium access control (MAC) device includes a first set of transmit pins, a second set of transmit pins, and a first encoder. The first set receives (i) first transmit data signals and (ii) first transmit control signals from a host. The first transmit data signals are received on a first subset of the first set. The second set outputs (i) second transmit data signals and (ii) second transmit control signals to a physical layer (PHY) device. The second transmit data signals are output on a second subset of the second set. The second subset includes fewer transmit pins than the first subset. The first encoder encodes two of the first transmit control signals received on two of the first set of transmit pins to generate one of the second transmit control signals output on one of the second set of transmit pins.
