1.4. Resource Utilization

Resource utilization changes depending on the parameter settings you specify in the H-tile Ethernet Hard parameter editor. This IP core is not as sensitive to parameter settings as other IP cores, because much of the functionality is in the Hard IP, but some parameters, such as the selection of a MAC+PCS, a PCS Only, an OTN 1, or a FlexE variation, do affect resource utilization on the device. If you select a MAC+PCS variation, the IP core requires additional resources to implement the additional functionality.

Note: Intel advises that resource utilization numbers are approximate, as the Intel® Quartus® Prime Pro Edition Fitter assigns resources based on the entirety of your design. The numbers below result from a single run on a simple design. Your results may vary.
Table 5.  IP Core FPGA Resource Utilization for Intel® Stratix® 10 Devices Lists the resources and expected performance for selected variations of the H-tile Ethernet Hard IP core in an Intel® Stratix® 10 device.

These results were obtained using the Intel® Quartus® Prime Pro Edition v18.1 software. All parameters are at their default values except the parameters listed in the table:

  • Ethernet rate
  • Ethernet IP layers
  • Enable AN/LT, Enable Auto-Negotiation, and Enable Link Training are either all set to the value of True or all to the value of False.
  • The numbers of ALMs and logic registers are rounded up to the nearest 100.
  • The numbers of ALMs, before rounding, are the ALMs needed numbers from the Intel® Quartus® Prime Pro Edition Fitter Report.
