Hello, I am getting 70 antennas inserted to protect a node that has only a single fanout. (the node in question is the buffered value of an io_in pin that writes to a register). Is this expected behavior, and are there any ways to reduce it? Increasing "GRT_MAX_DIODE_INS_ITERS" seems to have no effect on "DIODE_INSERTION_STRATEGY" 3. Changing DIODE_INSERTION_STRATEGY results in routing congestion issues (which is weird because its a relatively small design) I ask because I am getting setup violations that increasing "CLOCK_PERIOD" does not fix. Thanks
