#859 Illegal Overlaps in the Design
Issue created by

Description
When running a flow interactively on the OpenLane, at the run_magic_spice_export stage, I have faced an error like;
[ERROR]: There are illegal overlaps (e.g., routes over obstructions) in your design.

Reproduction Material
• List the commands used to run the design.
...
run_routing
write_powered_verilog
set_netlist $::env(routing_logs)/$::env(DESIGN_NAME).powered.v
run_magic
run_magic_spice_export
There is no message like reproducible package.
Expected behavior
After the routing process, I was not expecting to see any overlaps over routes and obstructions.
