1   Estimate the required logic, memory, and multiplier density. For more information, refer to the Device Variant section.
2   Reserve device resources for future development and debugging.

Intel® Agilex™ devices offer a range of densities that provide different amounts of device logic resources, including memory, multipliers, and adaptive logic module (ALM) logic cells. Determining the required logic density can be a challenging part of the design planning process. Devices with more logic resources can implement larger and potentially more complex designs, but generally have a higher cost. Smaller devices have lower static power utilization. Intel® Agilex™ devices support vertical migration, which provides flexibility.

You may observe 10% – 15% increase in resource utilization when you migrate your design from existing devices to Intel® Agilex™ devices. Review the resource utilization to find out which device density fits the design. Consider that the coding style, device architecture, and optimization options used in the Intel® Quartus® Prime software can significantly affect a design’s resource utilization and timing performance.

Select a device that meets your design requirements with some safety margin in case you want to add more logic later in the design cycle, upgrade, or expand your design. You might also want additional space in the device to ease design floorplan creation for an incremental or team-based design. Consider reserving resources for debugging.
