1.4. Performance and Resource Utilization

The following table shows the typical device resource utilization for selected configurations using the current version of the Intel® Quartus® Prime software. With the exception of M20K memory blocks, the numbers of ALMs and logic registers are rounded up to the nearest 100. The timing margin for this IP core is a minimum of 15%.

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.
IP Core Variation A B C
Parameter
Read Latency 0 0 3
Enable RS-FEC — On —
Enable flow control — Standard flow control, 1 queue Standard flow control, 1 queue
Enable link fault generation — — On
Enable preamble passthrough — — On
Enable TX CRC passthrough On — —
Enable MAC statistics counters — On On
Enable IEEE 1588 — — On
Table 5.  IP Core FPGA Resource Utilization for 50GbE Core for Intel® Arria® 10 DevicesLists the resources and expected performance for selected variations of the 50GbE core.

These results were obtained using the Intel® Quartus® Prime software v19.4.

  • 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.
