Calculating a timing delay in a repeater network in an electronic circuit. The repeater network comprises a plurality of driving cells. At least one loop comprising one or more pins and one or more driving cells for driving the loop is implemented. Each driving cell in the loop is arranged between two branches of the loop. For each driving cell, the loop is opened a plurality of times per driving cell, with one open at a time. A dedicated arrival time of a signal at each sink of the repeater network for the one open at a time per driving cell is calculated. The dedicated arrival time is stored. The calculation step and the storing step is repeated until the dedicated arrival time at each sink of the repeater network is available for each of the opens per driving cell.
