* New: In CRL Core, in RoutingLayerGauge, adds a new parameter "obstacleDw".
It represents the distance to add from the *edge* of a blockage segment
to the next *axis* of a routing track. This was previously computed as
the pitch minus the mimimum half wire width. This works if the pitch
is *equal* to the wire width plus the minimal distance (edge to edge).
But if the wire width is less, than it leads to too great a distance
around obstacles, making them bigger than they are. And potentially
blocking everything. To summarize:
before: obstacleDw = pitch - wireWidth/2 (deduced)
after: obstacleDw = explicitly setup, usually:
pitch - max(wireWidth)/2
Modify the Alliance configuration helper and the various kite.conf
file accordingly.
* New: In Kite, in BuildPowerRails, make use of "obstacleDw" to compute
the footprint of a blockage.
