Memory Block Specifications
To achieve the maximum memory block performance, use a memory block clock that comes through global clock routing from an on-chip PLL and set to 50% output duty cycle. Use the Intel Quartus® Prime software to report timing for the memory block clocking schemes.
When you use the error detection cyclical redundancy check (CRC) feature, there is no degradation in fMAX.
