I am getting an error in the openlane flow like:

[ERROR GRT-0076] Net CONTROL_LOGIC.SRAM12_WRAPPER.ram_din0\[0\] not properly covered.
Error: resizer_routing_timing.tcl, 67 GRT-0076
[ERROR]: during executing openroad script /openlane/scripts/openroad/resizer_routing_timing.tcl
[ERROR]: Exit code: 1
[ERROR]: Last 10 lines:
child process exited abnormally

What does this “not properly covered” mean?

Load the DEF file and search for that specific pin. Is that floating or not accessible during routing

Here is the def file. I think the macro is being placed outside the die area which is causing this issue?

Increase core area and try once
