Abstract
A system for re-ordering a scan chain of an electronic circuit design using an electronic design automation (EDA) tool includes a processor and a memory in communication with the processor. The scan chain includes a plurality of scan cells. All connections of the scan chain are disconnected. An output port of a first scan cell is connected to input ports of other scan cells to form a first set of scan cell combinations. A first scan cell combination is selected from the first set of scan cell combinations based on weighted averages of ordering parameters of each of the first set of scan cell combinations. The process is repeated to re-order the scan chain.
