Abstract
Mechanisms are provided for creating shift register definition from high-level model using high-level model simulation. The mechanisms initialize all potential scan chain latches, identify the latches in a given scan chain, and separate the scan chain latches into chunks. For each chunk, the mechanisms identify the latches within the chunk that change at each shift. The mechanisms isolate the scan path latch when divergence occurs.
