The final runtime signature is compared against a pre-calculated golden signature stored in hardware. Any mismatch indicates a fault. Memory BIST (MBIST)
Avoid being overly promotional or vague. Each section should explain the "why" and "how" of the technique. Use analogies like the "soldier & scout" for controllability/observability. Ensure the length is substantial - several thousand words, broken into digestible parts. The final output should serve as a reference article for professionals in VLSI design, hardware engineering, or students specializing in digital system design. Let me start writing.
