Challenges in LBIST validation for high reliability SoCs

Logic built-in self test (LBIST) is being used in SoCs for increasing safety and to provide a self-testing capability. LBIST design works on the principle of STUMPS architecture. STUMPS is a nested acronym, standing for Self-Test Using MISR (Multiple Input Signature Register) and Parallel SRSG (Shift Register Sequence Generator).
