Is anyone looking into TMR capabilities in OpenLane?

Triple modular redundancy to mitigate radiation effects on digital logic
I ended up finding CERN’s TMR Generator tool which can assist in modifying the RTL. The next question is how close will the redundant elements be placed in OpenLane. So that’s a rabbit hole I need to go down. You want them placed a min distance from each other so that a charged particle will only affect one and not all of the elements in the same circuit

There is no ongoing work for TMR. The placement problem sounds a lot like tapcell so perhaps that could be leveraged for your purpose.
