An other issue are the signals DVAL_IN, FVAL_IN and buffer_lock. If they are not synchronous to the clock you should/must synchronize them. Otherwise you will run into metastability problems with your fvalid_reg and lock_reg signal. 0 Kudos Copy link Reply Altera_Forum Honored Contributor...

My understanding is that the report_metastability feature of Quartus is not available for MAX II and MAX V devices. Does Altera provide a graph of MTBF vs. tMET or another way to manually perform metastability analysis for these devices?
