Various techniques are provided for routing signals to pins of components of programmable logic devices (PLDs). In one example, a computer-implemented method of routing signals in a PLD includes routing a plurality of signals to pins of a component of the PLD. At least two of the signals are routed to a same pin. The method also includes, for each of the signals routed to the same pin, determining a cost value associated with each of two or more pins. the method also includes, for each of the signals routed to the same pin, rerouting the signal to one of the two or more pins having the lowest cost value. The method also includes repeating the determining a cost value and the rerouting until no more than one signal is routed to a pin.
