Critical Issue
In the DCFIFO MegaWizard Plug-In Manager, on page 3 under Are the FIFO clocks synchronized?, the option Yes, the clocks are synchronized, do not add clock synchronization latency. is not available.
If you want to use this option, generate the megafunction with the No, the clocks are not synchronized, add latency to handle unrelated clocks. option. Edit the megafunction file generated and change the line:
dcfifo_component.clocks_are_synchronized = "FALSE" to
dcfifo_component.clocks_are_synchronized = "TRUE"
