05/14/2021, 10:14 AMHi, I'm running the openlane for doing the hardening of the user_project_wrapper. I completed successful the hardening of my user_project. But when I run the hardening with the user_project_wrapper I'm getting an error in the Step index 35 (Running Magic Spice Export from LEF...), the error is:
Copy code
[ERROR]: There are illegal overlaps (e.g., routes over obstructions) in your design.
[ERROR]: See /project/openlane/user_project_wrapper/runs/user_project_wrapper/logs/magic/35-magic_ext2spice.feedback.txt for more.t

05/14/2021, 2:45 PMWelcome to the club, as I am also facing same problem. Currently I could not find any solution because so called overlaps in feedback.txt are in user_project_wrapper that do not have any library cells.

05/14/2021, 4:04 PMPost placement report speaks of design density. I have observed that high density designs yield extraction errors.

05/15/2021, 11:20 AMI try to connect everything but still I have the same issue. Taking a closer look seems that magic finish, but is an error with the ext2spice simulation. I saw the comments of magic of how to use the feedback find etc, but seems that is the spice simulation, so I don't know how to access that part.

05/15/2021, 11:38 AMThis is not a DRC error, rather extraction error. In my personal opinion it is not fatal.

05/15/2021, 12:22 PMSo I manage to solve for me

05/15/2021, 12:22 PMI change some config in magic and now works.
set ::env(MAGIC_DRC_USE_GDS) 0
set ::env(MAGIC_EXT_USE_GDS) 1

05/15/2021, 12:24 PMthe tool finish but still I get a error. [ERROR]: Flow Failed.
Ivan Rodriguez
05/15/2021, 12:24 PMin the middle of the execution. but at the end I get [SUCCESS]: Flow Completed Without Fatal Errors.
Ivan Rodriguez
05/15/2021, 12:48 PMseems to be that only changin set ::env(MAGIC_EXT_USE_GDS) 1, makes my project work.

05/17/2021, 10:04 PM@Ivan Rodriguez Can you point me to your project to reproduce the magic extraction issue ?

05/18/2021, 5:13 AMHi, this is my git project
https://github.com/jaquerinte/caravel_radiation_harden
I manage at the end to have the GDS working but was by launching the project multiple times until I get a solution by chance.

05/18/2021, 6:32 PM@Ivan Rodriguez (cc: @jeffdi) On another note, the sub-module commit in your repo is pointing to an invalid commit. That is why the precheck platform is failing with an exception. You can fix this by running
make uninstallmake installi

05/18/2021, 6:50 PMOK I will try this ASAP. I was having issues updating the caravel sub module.

05/18/2021, 7:01 PMYes the issue for the pre-check is fix
