Abstract:
1. A computer-based crosstalk information detection method of a circuit board, the method comprising: reading a circuit board layout file from a storage device of a computing device, wherein the circuit board layout file comprises arrangement information of signal transmission lines of a circuit board; selecting a first signal transmission line from the circuit board layout file as a target line; receiving detection parameters set by a user, wherein the detection parameters comprise a height of a sample region for detecting aggressor lines of the target line, and a unit sample length along orientation of the target line; determining a second signal transmission line as an aggressor line of the target line based on the sample region; computing a distance between the target line and the aggressor line corresponding to each unit sample length; and defining the height of the sample region as a crosstalk space between the target line and the aggressor line corresponding to a unit sample length, if the distance is more than or equal to the height of the sample region, or defining the distance as the crosstalk space between the target line and the aggressor line corresponding to the unit sample length, if the distance is less than the height of the sample region.
