Level sensitive scan design (LSSD) solves testing and test-data generation problems at all levels of packagings, i.e., chips, boards, and system (1,2,3). In LSSD, it is customary to restrict the types of memory elements to random-access memories and shift register latch (SRL) stages. In certain applications, each SRL stage is configured with a linked pair of similar type D polarity-hold latches generally referred to as the Ll and L2 latches of the particular stage in (2,3).
