Router commands: stage1

Syntax: stage1 [options]

Execute stage1 routing. This works through the entire netlist, routing as much as possible but not doing any rip-up and re-route. Nets that fail to route are put in the failed nets list. The number of failed routes is printed.

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 one, 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.

netname
Route the named net only.
