User Guide
Figure 1–2 shows the directory structure after you install the Interlaken MegaCore
function, where <path> is the installation directory. The default installation directory
on Windows is C:\altera\<version number>; on Linux it is
/opt/altera<
version number>.
You can use Altera’s free OpenCore evaluation feature to evaluate the MegaCore
function in simulation before you purchase a license. You must purchase a license for
the MegaCore function only when you are satisfied with its functionality, and you
want to check performance in hardware and take your design to production.
After you purchase a license for the Interlaken MegaCore function, you can request a
license file from the Altera website at
www.altera.com/licensing and install it on your
computer. When you request a license file, Altera emails you a license.dat file. If you
do not have internet access, contact your local Altera representative.
Interlaken MegaCore Function Licenses
The Altera Interlaken MegaCore function is available to you through several different
licenses, depending on the variation you wish to generate. Licensing is based
primarily on aggregate bandwidth.
Table 1–7 shows the license required to program a
device with each supported variation.
After you acquire a license, you can compile and program your device with all the
variations that require that license. However, to program a variation that requires a
different license, you must acquire the additional license. You can generate, simulate,
and compile all MegaCore function-supported variations without a license, because
the Interlaken MegaCore function supports the Altera OpenCore evaluation feature.
