Abstract: A system for optimizing scan pipelining may include a processor and a memory. The processor may generate and insert, based on prior analysis of the physical layout of the circuit, an optimized number of pipeline stages between a first block and a second block in a hardware test design, a first scan chain including at least one pipeline stage of a head pipeline stage or a tail pipeline stage. The processor may insert a plurality of flip-flops into the first scan chain. The processor may determine at least one clock to be used for the at least one pipeline stage, using the plurality of flip-flops so as to eliminate the need of a lockup element between the at least one pipeline stage and the plurality of flip-flops. The processor may generate, based on the at least one clock, a second scan chain that connects the at least one pipeline stage and the plurality of flip-flops.
