Zusammenfassung:	A channel routing method (200) comprises computing channel parameters (210), classifying a channel complexity and estimating a channel height (220), optionally, determining a trunk placement direction (225), assigning tracks and layers (230), determining a quality function QF (240), and optimizing (250). The channel complexity is classified using predetermined weighting parameters (a1 to a4). This classification selects a significance vector n. In the assigning step (230), the vector n is combined with the channel parameters to a criterion. The criterion is used the select the most suitable assignment. In repetitions of assigning, determining QF and optimizing steps, the significance vector n and, optionally, QF are modified. The repetition are stopped upon compliance of a breaking condition which can refer to QF.
