The rows are cut around the macro according to the halo so there are no legal placement sites inside the halo. I can't see any instances of an antenna diode...
Diodes in yellow: 
The diode must in a row to be marked FIRM: ``` legally_placed = legally_placed && diodeInRow(inst_rect); ... if (core_area.contains(inst_rect) && !sink_inst->getMaster()->isBlock() && legally_placed) { antenna_inst->setPlacementStatus(odb::dbPlacementStatus::FIRM); ```

One example: // (dbGCellGrid|dbTrackGrid)::getGridPattern[XY] %apply int& OUTPUT { int& origin_x, int& origin_y, int& line_count, int& step }; is in tcl only
@arlpetergadfort does the new pdn resolve this?
global_placement has a -max_phi_coef but it is rather obscure though you can try different values. What happened when increased the core area? Did the overflow reach a lower level or...
