同意你的意见。如果手工能做的ECO基本上要比自动做出来的要好。当手工很费时间或根本不可能，那只能用工具帮助。GOF有脚本模式可能也可用于手工，我还在试。所以我问 dfcan 有什么心得在脚本运用上。
我看过dorado 的ECO介绍，他们有个例子，自动用了25, 手工用了22. 不知谁可也弄到他们的工具。

Has anyone tried the usage of stitch_scan_chain? How to verify the new scan chain is good? Thanks.

The usage should beset_top("most_top");
stitch_scan_chain("-to", "a_flop_for_scan_insertion");
It looks like all new flops will be inserted to one scan chain. I think there needs some improvement here.
Because I would like one group of flops inserting to one chain, and the other group of flops inserting to the other chain.


After the scan is done, you need run DftAdvisor or other DFT tool to verify the new scan chains.

感谢 dfcan!

这是比较典型的出错信息。新的网表有了新的INSTANCE NAME。 你应该把新网表的INSTANCE NAME跟ECO网表一样。就是说uretime_eco6759 应该也出现在ECO网表里。或可能ECO网表里的INSTANCE NAME 是uretim。也可以在综合时，把FLOP所在的模块扁平化，FLATTEN。

好東西, 不用破解, 感謝
