Hi all, I need help at chip integration stage of user_project_wrapper. I am using provided config.tcl. The flow fails at following step. [INFO]: Klayout XOR Complete [INFO]: Running Magic Spice Export from LEF... [INFO]: current step index: 35 With the following errors Processing user_project_wrapper Extracting user_proj_example into user_proj_example.ext: Extracting user_project_wrapper into user_project_wrapper.ext: user_project_wrapper: 760 fatal errors Total of 760 errors (check feedback entries). exttospice finished. Using technology "sky130A", version 1.0.150-0-gb06f0f2 [ERROR]: There are illegal overlaps (e.g., routes over obstructions) in your design.

I've only seen this in GDS files that have problems in them. When you hardened the GDS for your user project did you get any errors then?

No, hardened one was very clean, I am attaching for reference. At line 6544, [INFO]: No Illegal overlaps detected during extraction.
