Abstract
In one aspect, techniques are disclosed for identifying and notifying a circuit designer of signal traces in an integrated circuit design that are closer to each other than a proximity threshold. It is desirable that signal traces be separated from each other by at least the proximity threshold to reduce inter-signal crosstalk to an acceptable level. Such notification may occur either dynamically (while the circuit designer is designing the circuit) or through a report generated after the circuit design has been generated. In another aspect, techniques are disclosed for identifying and notifying the circuit designer of the signal traces that are closest to a reference signal trace. Such notification may provide the circuit designer with feedback about regions in the circuit design which are congested and which may therefore produce an unacceptable level of crosstalk.
