1.10. V-Series Recommended Speed Grades
Altera recommends setting the Quartus® Prime Analysis & Synthesis Settings Optimization Technique to Speed when the Application Layer clock frequency is 250 MHz. For information about optimizing synthesis, refer to Setting Up and Running Analysis and Synthesis in Quartus® Prime Help. For more information about how to effect the Optimization Technique settings, refer to Area and Timing Optimization in volume 2 of the Quartus® Prime Handbook.
