Chapter 2
Licensing the Core
This chapter provides instructions for obtaining a license for the CAN core, which you
must do before using the core in your designs. The CAN core is provided under the terms
of the Xilinx LogiCORE Site License Agreement
, which conforms to the terms of the
SignOnce
IP License standard defined by the Common License Consortium. Purchase of
the core entitles you to technical support and access to updates for one year.
Before you Begin
This chapter assumes that you have installed all required software specified on the CAN
product page.
License Options
The CAN core provides three licensing options. After installing the required Xilinx ISE®
software and IP Service Packs, choose a license option.
Simulation Only
The Simulation Only Evaluation license key is provided with the Xilinx CORE Generator™
tool. This key lets you assess core functionality with either the example design provided
with the CAN core, or alongside your own design and demonstrates the various interfaces
to the core in simulation. (Functional simulation is supported by a dynamically generated
HDL structural model.)
Full System Hardware Evaluation
The Full System Hardware Evaluation license is available at no cost and lets you fully
integrate the core into an FPGA design, place-and-route the design, evaluate timing, and
perform functional simulation of the CAN core using the example design and
demonstration test bench provided with the core.
In addition, the license key lets you generate a bitstream from the placed and routed
design, which can then be downloaded to a supported device and tested in hardware. The
core can be tested in the target device for a limited time before timing out (ceasing to
function), at which time it can be reactivated by reconfiguring the device.
Cannot use this in production programs.
