Abstract

The invention relates to a delay calculation method for wiring nets of an electronic circuit, wherein a net within an electronic circuit comprises a driver pin and a receiving pin being coupled by at least one loop, the loop comprising a first branching path and a second branching path electrically parallel to the first branching path, wherein at least a first and a second branching point connect the branching paths. The method comprises the steps of disconnecting each branching path once at a time at a specific point in said the at least one loop which connects a driver to at least one specific receiving pin; calculating a delay value of a signal connection between the driver pin and each of the receiving pin for each of the disconnected branching paths of each loop; storing maximum and/or minimum calculated delay values; and applying at least one of the delay values for static timing analysis of the electronic circuit.
