A method is provided for assigning signals to input pins of a component subject to asymmetric delays. A latency is determined for each signal-pin combination of the plurality of signals and plurality of input pins. The latency is determined as a function of an arrival time of the signal, a time to route the signal from to the input pin, and a time attributable to processing by the component. A latency threshold is selected. Signal to pin assignments using only signal-pin combinations having latencies less than or equal to the latency threshold are analyzed to determine if a one-to-one signal-to-pin assignment exists that includes all signals. The latency threshold is increased and the analysis is repeated until a valid one-to-one signal-to-pin assignment is found.
