9-6-4: Maze Routing
Maze routing is done with a single arc, and cannot change layers. Therefore, if the two ends of an unrouted arc are not able to connect to a common layout arc, routing will fail.
Maze routing is done one wire at a time, and may fail if no path can be found. Therefore it may be preferable to route the unrouted wires one-at-a-time in order to better control the process.
Note also that maze routing constructs an array which is the size of the route, and searches the array for a routing path. Therefore, long wires will use large amounts of memory and time.
For an example of maze routing, open the Samples library and edit the cell "tool-RoutingMaze" (you can read the library with the Load Sample Cells Library command, in menu Help). This cell has a number of unrouted wires that can be routed.
