I’m getting the following warning during the detail routing phase. Is it important (I have no LVS issues)?

[WARNING DRT-0225] core.CPU_Dmem_value_a5\[11\]\[5\] 1 pin not visited, fall back to feedthrough mode.
[WARNING DRT-0225] net3144 1 pin not visited, fall back to feedthrough mode.
[WARNING DRT-0225] net3467 1 pin not visited, fall back to feedthrough mode.

@User As there is no DRC and LVS issue it should be fine. I also observed similar warning during SRAM integration. Discussion say's it should be fine https://github.com/The-OpenROAD-Project/OpenROAD/issues/1197#issuecomment-948608536
