Arguments

Value Returned

f_wrongWayTax

Represents a multiplier to the internal wrong-way cost set by the router. A tax greater than 1.0 tends to reduce the amount of wrong-way routing and increase the number of vias used. A tax less than 1.0 and greater than 0.0 tends to increase the amount of wrong-way routing used.
