Replace broad GPIF/radio false paths with 10 ns datapath-only maximum delays between the 100 MHz GPIF clock and the generated SISO/MIMO radio clocks.
Preserve physical control of asynchronous CDC paths without overriding the more-specific XPM FIFO CDC constraints.
Create generated clock copies on the shared radio BUFGMUX output and mark the full-rate SISO and divide-by-two MIMO modes logically exclusive.
This prevents static timing from attempting impossible cross-mode hold fixes while retaining valid timing relationships outside the shared clock tree.
