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.
