1.3. Resource Utilization

Resource utilization changes depending on the parameter settings you specify in the Low Latency E-Tile 40G Ethernet parameter editor. For example, if you turn on statistics counters in the Low Latency E-Tile 40G Ethernet parameter editor, the IP core requires additional resources to implement the additional functionality.

Table 4.  IP Core Variation Encoding for Resource Utilization Table"On" indicates the parameter is turned on. The symbol "—" indicates the parameter is turned off or not available.

Table 5.  IP Core FPGA Resource Utilization in Intel® Stratix® 10 deviceLists the resources and expected performance for selected variations of the Low Latency E-Tile 40G Ethernet IP core in a Intel® Stratix® 10 device.

These results were obtained using the Intel® Quartus® Prime 20.1 software version.

  • 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.
