Abstract

Techniques and systems for automatic net grouping and routing are described. Some embodiments can determine a set of net groups by automatically grouping nets that have (1) a same pin count, (2) a pin direction type that is in a predefined set of pin direction types, and (3) a pin order type that is in a predefined set of pin order types. Next, the embodiments can generate routing guidance by performing trunk planning for each net group. The embodiments can then perform detailed routing for each net in each net group by using the routing guidance.
