DFT Compiler软件Performing Scan Extraction功能

LCS527

请问各位大佬是如何理解user guide里面这段话的，
Performing Scan Extraction
Scan extraction is the process of reading in an ASCII netlist that lacks test attributes, then
analyzing the netlist to determine the scan chain structures. After identifying the scan
structures, you can write out test model and test protocol files for design reuse.
是不是说我在不知道其他测试条件的情况下，只要把插入扫描链的网表读进去，任何描述出扫描链的输入输出端口，
软件是不是就可以自动分析，帮我写出可用来产生patterns的test protocol 。
