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： In general, in one aspect, the disclosure describes an apparatus having an averager to receive differential output voltages of a transmitter and generate an average transmitter output voltage. A comparator is to compare the average transmitter output voltage to a reference voltage and generate a difference therebetween. An integrator is to integrate the difference between the average transmitter output voltage and the reference voltage over time. The integrated difference is fed back to the transmitter to bias the transmitter.

摘要： A circuit board may include first and second sides, a plurality of circuit board layers between the sides, and a plurality of signal traces located in respective circuit board layers. The circuit board layers and the signal traces may extend from a first component connection region at the first side of the circuit board to a second component connection region at the first side of the circuit board. The signal traces may thus form stubless signal paths through the circuit board between the component connection regions. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
