retime failed with error msg "Failed on find_unique_design"

archive

I have set attribute retime to a certain design

set_attr retime 1 [find / -subdesign some_design]

after elaboration. However I get following error message after the generic synthesis:

Failed on find_unique_design

The script is structured as follows;
1. read libraries and set library
2. read don't use cells
3. read_hdl
4. elaborate
5. read constraints
6. set costs groups/path groups
7. set_attr retime true [find / -subdesign *]
7. run generic synthesis
8. run technology mapping etc...

I have set this attribute to only one subdesign. find_unique_design is an internal command I think.

Do you have any idea?

    Thanks for the update for the rest of us watching the forum Sporadic Crash. Do not worry about the details. If your company is as security happy as mine, I certainly empathize . . .
    I will definitely watch out for it but hopefully they will remedy soon from your comments.

    take care,
