(1) To achieve the maximum memory block performance, use a memory block clock that comes through global clock routing from an on-chip PLL
set to 50% output duty cycle. Use the Quartus II software to report timing for this and other memory block clocking schemes.
(2) When you use the error detection CRC feature, there is no degradation in FMAX.
