Router commands: stage3

Syntax: stage3 [options]

Execute stage3 routing. This works through the entire netlist, ripping up each route in turn and re-routing it. 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 three, 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.
