Trouble when using "write_layout_scan" in DC and "detach scan chain" in Astro!:?:
In dc_shell-t,my design has been synthesized including "insert_scan",also,design.db and design.sv have been generated.
In order to get scan chain information for Astro,check_test、set_scan_configuration -prtool avant
write_layout_scan have been runnd,in sequence.
After what has been done above,I got design.def、design_pre.scr and design_post.scr in hand.
Then,in Astro,some errors come up when loading "design.def".
Errors said that Astro can't find some cell instances or ports that specified in "design.def" file.

My question is what is problem with my DC or Astro?
How could I deal with them??

Somebody help me!I have been troubled for several days!
