This tutorial uses JNEye to run an OIF VSR 28 Gbps link simulation using Altera’s Arria 10 GT devices.
The link topology is shown in the following figure.
Note: This link configuration and simulation are for demonstration purposes. It is not intended for
actual implementation. Consult Altera design guidelines for actual high-speed link design and
implementation.

Methodology
This simulation emulates an Altera Arria 10 GT transmitter (with embedded package model), an OIF 25
Gbps VSR channel (with crosstalk), and an Altera Arria 10 GT receiver (with embedded package model).
The link operates at 28 Gbps with a transmitter differential output voltage (V
OD
) of about 1000 mV. The
test pattern is PRBS-31 and the BER target is 10
–15
. Per Arria 10 GT specifications, the transmitter has a 5-
tap FIR and the receiver has CTLE and a 1-rap DFE (at 28 Gbps). DFE is not required in the OIF VSR
standard, so DFE is disabled in this tutorial.
