How to fix certain Routing?

In my place&route implementation in SoC Encounter, I'm placing certain instances and fix their positions by the command placeInstance -fixed , then I route between them manually by long close metals with minimum DRC (It's intentional for my task). The problem is that when I continue the implementation (placing) the standard cells and (optimizing) Design, some of those connections are removed. Is there a way to fix those metal wires I drew manually so they are still connected till the end after all different steps?

Hi Mahmoud,

You will need to mark all the wires of such nets as fixed. You can use dbGet commands
