ROUTER_EFFORT_MULTIPLIER
ROUTER_EFFORT_MULTIPLIER
Type
Controls how quickly the router tries to find a valid solution. The default value is 1.0
and legal values must be greater than or equal to 0.25. Values higher than 1.0 may
improve routing quality at the expense of run-time on difficult-to-route circuits.
Values lower than 1.0 can reduce router run-time, but usually reduces routing quality
slightly.
