Welcome to my blog

My name is Sven Andersson and I
work as a consultant in embedded
system design, implemented in ASIC
and FPGA.
In my spare time I write this blog
and I hope it will inspire others to
learn more about this fantastic field.
I live in Stockholm Sweden and have
my own company

FPGA design from scratch. Part 92
LEON3 soft processor

I have just started a new FPGA design project. This time we will use the Leon3 soft processor from Gaisler and build a system around it. For that reason I have ordered a new development board from Xilinx, the Spartan-6 FPGA SP605 Evaluation Kit.

Unpacking the box

Here is what's in the box.

The board itself.

The documentation

In the box we find these two documents, all other documents are found on the USB flash drive that is included in the kit.

Here is the content of the USB flash drive.

Installing the ISE Design Suite software

The software can be installed from the DVD included in the kit or from the Xilinx software download page. For more information about downloading and installing the software from the download site see part 51.

To install the software from the DVD, insert the DVD in your computer's DVD reader. The DVD contains the following directories and files.

We will install the Linux version of the software. To start the installation double-click the xsetup icon and follow the instructions.

 Installing the license file

A software voucher is included with the SP605 evaluation kit. The voucher contains the code that is used to create a device-locked and node-locked software license for the ISE Logic Edition. To create a license goto the Xilinx Product Licensing.

Enter the 22-digit code from the voucher in the field shown here above and click Redeem Now. For more information see the document "Getting Started with the Xilinx Spartan-6 FPGA SP605 Evaluation Kit" and part 51 in this blog.

Find out more

I will continue this blog about LEON3 from the Realtime Embedded website.

The main reason for using LEON3 is that it is the open source.
February 13, 2012   03:21 PM PST
is there any particular reason for using LEON?
