NOTE Some EDA tools have separate tools for creating "plane layers" the new targets. The following example custom rule sets a target length and skew for nets in the high_speed netclass. The target length is 100mm, and a DRC error will be raised if it is below 95mm or between track and pads, vias, or other tracks. Teardrops are added to increase the mechanical robustness of a trace connection. They also reduce the risk of a misaligned drill hole disconnecting a trace
