摘要:
The present invention relates to a method for performing a test case with at least one LBIST engine on an integrated circuit with a plurality of storage elements and logic circuits interconnected according to a predetermined scheme. The LBIST engine is at least partially built up by storage elements and/or logic circuits. At least one scan chain is formed as a series of selected storage elements and the other storage elements are used for the LBIST engine or a part of said LBIST engine in a testing mode. The scan chain is driven by a test pattern and the LBIST test case is testing those parts of the logic circuits corresponding to the storage elements of said scan chain.
