Router commands: stage2

Syntax: stage2 [options]

Execute stage2 routing. This stage works through the failed nets list, routing with collisions, and then ripping up the colliding nets and appending them to the failed nets list.

The number of failed nets remaining is printed on exit.

The following options are understood.

-d
Draw the area being searched in real-time. This slows down the algorithm and is intended only for diagnostic use. Not implemented.

-s
Single-step stage two, i.e., do one route per call, incrementally.

-m[ ]value
The value follows the option character with or without intervening white space. It can be an integer 0 or larger, and will set the search mask size. It can also be set to one of the following keywords, where only the first character is significant.
n[one]
Don't limit the search area.
a[uto]
Select the mask automatically.
b[box]
Use the net bounding box as a mask.

-f
Force a terminal to be routable.

-l N
Fail route if the solution collides with more than N nets.

-t N
Keep trying N additional times.

netname
Route the named net only.
