Abstract

See full text

Methods of a scan partitioning a circuit are disclosed. One method includes calculating a power score for circuit cells within a circuit design based on physical cell parameters of the circuit cells. For each of the circuit cells, the circuit cell is assigned to a scan group according to the power score for the circuit cell and a total power score for each scan group. A plurality of scan chains is formed. Each of the scan chains is formed from the circuit cells in a corresponding scan group based at least in part on placement data within the circuit design for each of the circuit cells. Interconnect power consumption can be assessed to determine routing among circuit cells in the scan chains.
