SLM Built-in Self-Test IP

Enables structural testing of logic during in-system operation

Synopsys SLM BIST IP delivers a solution for in-system self-test of digital designs where functional safety is critical, such as automotive, medical, and aerospace applications. BIST family consists of LBIST and XLBIST variants. LBIST is targeted for Analog Mixed-Signal designs where digital content is not heavy, making compact BIST design necessary. XLBIST has X-tolerant capability with compression making it suitable for large digital designs. Both products come with ASIL D ready FuSa certification. TestMAX ATPG is used to generate seed & signature needed by BIST IP.
