1.4.1. Arria 10 Resource Utilization

Resource utilization changes depending on the parameter settings you specify in the LL 100GbE parameter editor. For example, if you turn on pause functionality or statistics counters in the LL 100GbE parameter editor, the IP core requires additional resources to implement the additional functionality.

Table 5.  IP Core FPGA Resource Utilization in Arria 10 Devices Lists the resources and expected performance for selected variations of the LL 100GbE IP core in an Arria 10 device.

These results were obtained using the Intel® Quartus® Prime software v16.1.

  • 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 Fitter Report.
