Random single hold violations on Arria V design that doesn't push timing or util. ???

Hi - I have a design that uses about 20% of the FPGA Fabric on an ArriaVSoc. I've added my own logic to the GHRD. It doesn't push timing (my logic is 100MHz or less), or utilization (see above, eve...

Can't Quartus resolve hold vios between dsp blocks?
