    摘要: A method for performing analysis of electrical signals in a system is disclosed. The system includes at least two circuit elements between which an electrical signal is transmitted. The method converts the electrical signal to dual optical signals, one of which is converted back to an electrical signal for receipt by the intended circuit element. The second optical signal may be transmitted a great distance, relative to electrical signals, allowing for remote analysis of the signal. The loss in converting the electrical signal to an optical signal, then back to an electrical signal is low compared to other debug methods. The method may be performed with high-speed signals.

    摘要: A receiving device within a digital electronic system includes a sampling unit, a voter block, and a local clock phase adjustment unit. The sampling unit samples an input line at three points in time at intervals of one half of a bit period. The sampling unit delivers the values obtained in the sampling process to the voter block. The voter block determines whether to deliver an up or a down vote to the local clock phase adjustment unit. The voter block communicates with the local clock phase adjustment unit via up and down control signals. The local clock phase adjustment unit determines whether the local clock phase should be adjusted, and if so, whether to advance or delay the local clock phase. If certain meta-stable conditions are observed by the voter block, the voter block will vote in one direction in order to push the system out of the meta-stable condition.
