Hi all i builted a large design for Startix IV 530. i'm using up to 630 DSP blocks in my design. if let it run (compile) normaly, i get "altera_reset_synchronizer_int_chain_out" timming fallin...

13 years agoThat's not good, your just sweeping issues under the "false path" rug.
You should set a false path between the reset input signal and the synchronization registers _IF_ the reset signal is asynchronous in respect to the target clock. If you still get failing paths after that, then you have a problem that affects timing and you need to take care of it that way. Maybe the reset output needs to be driven to a global clock signal and Quartus is failing to do so automatically?
