    • A differential signal transmission device transmits N differential signal pairs from a differential signal generator to a number of receiving terminals. The N differential signal pairs include N positive signals and N negative signals. The N positive signals are clustered at a first positive clustering point. The first positive clustering point is connected to a second positive clustering point via a first matching resistor. The second positive clustering point is grounded via a first grounding resistor, and outputs a number of positive signals to the number of receiving terminals respectively. The N negative signals are clustered at a first negative clustering point. The first negative clustering point is connected to a second negative clustering point via a second matching resistor. The second negative signal clustering point is grounded via a second grounding resistor, and outputs a number of negative signals to the number of receiving terminals respectively.

    • In a method of optimizing parameters of electronic components on printed circuit boards (PCBs), a first experiment table for m variables of one type of parameter of P electronic components on a PCB is designed using n values of each variable and the RSM. P EHs of each first experiment are obtained by simulating, and P EH empirical formulas are computed according to the P EHs. A second experiment table for the m variables is designed using n′ values of each variable and the full factorial design, and P EHs of each second experiment are computed using the P EH empirical formulas. Experiments, all the P EHs of which are greater than 1, are filtered from the second experiment tables, and an average EH of each filtered experiment is computed to pick an experiment the average EH of which is the greatest. The values of the m variables in the picked experiment are considered as optimized.

    • A computing device and a method reads a circuit board layout file from a storage device, and selects a first signal transmission line from circuit board layout file as a target line. The computing device and method computes a distance between the target line and the aggressor line corresponding to each unit sample length. If the distance is more than or equal to a height of a sample region, the computing device and method defines the height of the sample region as a crosstalk space between the target line and the aggressor line corresponding to a unit sample length. Otherwise, if the distance is less than the height of the sample region, the computing device and method defines the distance as the crosstalk space between the target line and the aggressor line corresponding to the unit sample length.
