DFT再了解(五)

DFT Compiler Flows Supported

Top-Down
Scan insertion is performed at the top-level for the entire
design in one step

Bottom-Up
Scan insertion is performed at the block-level and
results are later combined at the top-level

Unmapped Flow
Scan insertion begins with an unmapped (RTL) design

Mapped Flow
Scan insertion begins with a mapped (gate-level) design

Extraction (Inference)
Scan insertion begins with a design that has existing
scan chains already inserted
