net drills embedded in laminate if the distance from the edge of
the drill to the nearest copper is less than pp_d2c.

Purpose |
A hole to be isolated from power or ground planes must be kept apart from copper. The required distance is typically larger than regular spacing due to the higher than usual current. |
Function |
Reports other net drills embedded in laminate if the distance from the edge of the drill to the nearest copper is less than pp_d2c. |
ERF Parameters |

ERF Variables |
classify_via2c = 1 |
Constraint |

Limitations |
In positive power and ground layers, no associated copper feature is reported. |
