Abstract

A first scan pattern may be received to test a first circuit block in an integrated circuit (IC) design and a second scan pattern may be received to test a second circuit block in the IC design. A first length of the first scan pattern may be different from a second length of the second scan pattern. The first scan pattern, the second scan pattern, or both the first scan pattern and the second scan pattern may be modified to make lengths of the first scan pattern and the second scan pattern equal.
