This function is used to automatically link two pins.

Args

waypoints:

to appoint the auto link's waypoint that auto link go through.

min_distance:

default minimum distance before turning around.

start_distance:

default minimum distance (from start port) before turning around.

end_distance:

default minimum distance (from end port) before turning around.

metal_line_type:

a registry contains metal line type for a specific layer.

auto_vias:

a registry contains functions which generate vias for a specific layer pair.

flyline_layer:

the flyline layer. If the link fails, a flyline is created between the ports.

target_length::

this link’s length.

Usage:

fp.LinkBetween(start=cell1["ep_1"], end=cell2["ep_0"], start_distance=40,
                metal_line_type=[(0, TECH.METAL.MT.W10)],)

Returns

An instance of LinkBetween or None when start and end matches directly.
