Asked Questions
This section below explains the frequently asked questions of Nios II
Embedded Evaluation Kit.
Why is my SOF time-limited?
Several IP cores in the example designs (Nios II processor core, DDR
SDRAM memory core, TSE MAC core) are evaluation versions available
as OpenCore Plus IP cores. OpenCore Plus hardware evaluation supports
the following two modes of operation:
● Tethered —requires a JTAG connection between your board and
the host computer. If tethered mode is supported by all
megafunctions in a design, the device can operate for a longer
time or indefinitely
● Untethered —the design runs for a limited time
To generate non time limited SOF files you will need to purchase shipping
licenses for any OpenCore Plus IP cores in your system. Contact your
local sales offices to purchase the license.

What are Ready-to-Run Demonstrations?
Ready-to-run demonstrations are binary (flash) files of processor systems
that can be programmed to flash or selected and loaded from the LCD
touch panel. Ready-to-run demonstrations provide a quick and easy way
to evaluate Nios II based processor systems built for applications such as
automotive graphics, industrial controls, consumer graphic user
interfaces and more.
Most ready-to-run demonstrations have been provided by Altera's
partners and showcase IP, operating systems and software tools.
Where can I find Ready-to-Run Demonstrations?
For the Nios II Embedded Evaluation Kit (NEEK), there are many
ready-to-run demonstrations available on the sd-card. A menu listing all
the demonstrations stored on the SD-Card appears when the NEEK is
first powered up. The ready-to-run demonstrations that you see on the
