1. Quick Start Guide

Updated for:
Intel® Quartus® Prime Design Suite 24.3
IP Version 8.1.1
The F-Tile Interlaken Intel® FPGA IP provides a simulation testbench and a hardware design example that supports compilation and hardware testing. When you generate the design example, the parameter editor automatically creates the files necessary to simulate, compile, and test the design.

The testbench and design example supports NRZ and PAM4 mode for F-tile devices. The F-Tile Interlaken Intel® FPGA IP generates design examples for the following supported combinations of number of lanes and data rates.

Table 1.  IP Supported Physical Combinations of Number of Lanes and Data RatesThe IP supports the following combinations in the Quartus® Prime Pro Edition software version 24.2.

For FGT PAM4 transceiver mode:

  • Physical configuration of 2 lanes x 53.125 Gbps, corresponds to IP GUI settings 4 lanes x 26.5625 Gbps.
  • Physical configuration of 10 lanes x 56.25 Gbps, corresponding to IP GUI settings 20 lanes x 28.125 Gbps.
For FHT PAM4 transceiver mode:
  • Physical configuration of 1 lane x 106.25 Gbps, corresponds to IP GUI settings 4 lanes x 26.5625 Gbps.
Number of Lanes Lane Rate (Gbps)
6.25 10.3125 12.5 25.78125 53.125 56.25 106.25

Note: For designs with 56.25 Gbps data rate, you may observe a minimum pulse width violation when using a device with a speed grade of -3.
Figure 1. Development Steps for the Design Example
The F-Tile Interlaken Intel® FPGA IP core design example supports the following features:
  • Internal TX to RX serial loopback mode
  • Automatically generates fixed size packets
  • Basic packet checking capabilities
  • Ability to use System Console to reset the design for re-testing purpose
