33.2.4.3. Hardware Design and Target Device
The target device affects the maximum achievable clock frequency of a hardware design. Certain device families achieve higher fMAX performance than other families. Furthermore, within a device family, faster speed grades achieve higher performance. The SDRAM controller core can achieve 100 MHz in Intel FPGA high-performance device families, such as Stratix® series. However, the core might not achieve 100 MHz performance in all Intel FPGA device families.
The fMAX performance also depends on the system design. The SDRAM controller clock can also drive other logic in the system module, which might affect the maximum achievable frequency. For the SDRAM controller core to achieve fMAX performance of 100 MHz, all components driven by the same clock must be designed for a 100 MHz clock rate, and timing analysis in the Quartus® Prime software must verify that the overall hardware design is capable of 100 MHz operation.
