Abstract
A channel routing method ( ) comprises computing channel parameters ( ), classifying a channel complexity and estimating a channel height ( ), optionally, determining a trunk placement direction ( ), assigning tracks and layers ( ), determining a quality function QF ( ), and optimizing ( ). The channel complexity is classified using predetermined weighting parameters (a to a ). This classification selects a significance vector n. In the assigning step ( ), 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.
