Hi, I tried to "make my_design" in caravel_user_project to harden my design, but it stopped with "invalid index for position". Does anyone know how to fix this? Also, I don't know if this helps, but I get a lot of warnings about "failed placement failed on ~" during the process. Best Regards.

Hi @Cra2yPierr0t set below variable in config.tcl and try.

set ::env(GLB_RESIZER_TIMING_OPTIMIZATIONS) 0
