  • Patent number: 7155696
    Abstract: The present invention relates to a method of interconnection routing for preventing crosstalk. The method comprises the following steps. Providing an aggressor connection path as a first net. Providing a victim connection path according to the requirements of a second net. Determining a voltage ramp time of the aggressor connection path, a victim total length of the victim connection path, a coupled wire length between the aggressor connection path and the victim connection path, and an equivalent load corresponding to the victim connection path. Evaluating a noise metric according to the voltage ramp time, the victim total length, the coupled wire length and the equivalent load. Modifying the victim connection path to shorten the coupled wire length if the noise metric is greater than a pre-determined value. Finally designating the victim connection path as the second net if the noise metric is less than the pre-determined value.
