Abstract
An apparatus and method for generating scan chain connections for an integrated circuit (IC) in order to perform scan diagnosis of a manufactured IC chip, in which the scan chain connections are determined using functional path information among the flip flops of the IC design corresponding to the IC chip. A plurality of flip flops included in the IC is grouped into at least a first group and a second group based on the functional path information among the flip flops. At least one scan chain is generated from at least a portion of the flip flops in the first group. At least one scan chain is generated from at least a portion of the flip flops in the second group.
