Abstract: This application relates to a method of routing circuit paths of an integrated circuit, IC. The IC comprises a plurality of circuit elements and a plurality of circuit paths connecting the circuit elements. The method comprises steps of: receiving a representation of the IC, comparing, based on the representation, the circuit elements of the IC against a set of reference circuit elements, classifying the circuit paths of the IC into a plurality of categories based on a result of the comparison, and routing the circuit paths of the IC in accordance with their respective categories. The application further relates to a computer-readable storage medium comprising a computer program that makes a computer perform the steps of said method when executed and to an apparatus for routing circuit paths of an IC.
