A bounding-box spatial hash (broad phase) with exact IntBox-intersection narrow phase, replacing the exact router's occupancy grid. Supports insert/remove-owner and overlap/region queries, a clearance_conflict test (strict 2-D overlap of the clearance-expanded box, so tiles exactly a clearance apart are allowed), and has_violation for the whole-board DRC check. Tiles are tagged routed vs static so pad-vs-pad spacing in the source design is not counted as a routing violation.

"""Board data model for freeroute.
|
|
|
|
The data model a parsed DSN produces and the (future) router operates on:
|
|
layers, units, coordinate transform, nets, clearance matrix, the item hierarchy,
|
|
and the :class:`BasicBoard` container. :func:`build_board` constructs a board
|
|
from a :class:`~freeroute.dsn.model.DsnBoard`.
|
|
|
|
The routing operations (``RoutingBoard``) and the spatial ``ShapeSearchTree``
|
|
belong to the router phase.
