    Abstract: A method for verifying coupling in a differential via pair group includes identifying a differential via pair group in a design database and identifying a victim differential via pair in the differential via pair group. All other differential via pairs in the differential via pair group are identified as culprit differential pairs. The differential via pair group includes at least one culprit differential via pair. The method also includes obtaining a total coupling threshold level and calculating a total coupling factor for the victim differential via pair within the differential via pair group. The method also includes flagging the victim differential via pair if the calculated total coupling factor exceeds the total coupling threshold level.

    Abstract: Solid-state waveguide structures are disclosed to detect and/or encode very fast (picosecond) optical signals. The waveguides are appropriately configured to cause very fast signals to interact with interrogation or erasure pulses by a two photon absorption mechanism. The coincidence of the pulses in particular regions causes erasure and/or changes in the waveguide conductivity which can be measured conventionally by parallel circuitry.

    Abstract: A method for verifying coupling in a differential trace pair group includes reading victim properties of a victim differential trace pair and culprit properties of a plurality of culprit differential trace pairs from a circuit design database. The method also includes calculating a plurality of coupling factors based on the victim properties and the culprit properties, one from each of the plurality of culprit differential trace pairs to the victim differential trace pair. The method also includes calculating a total coupling factor for the victim differential trace pair based on the plurality of coupling factors, and flagging the victim differential trace pair if the total coupling factor exceeds a total coupling threshold level.
