New Horizons









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 61
Looking for a new development board

Now when we are using the latest Design Suite from Xilinx, we can't use a more than 5 years old development board, I just realized. So I started to look for a
new board and found this one:



The Avnet
Spartan-6 LX9 MicroBoard

Key Features
  • Spartan-6 XC6SLX9-2CSG324C FPGA
  • 64 MB LPDDR SDRAM
  • 128 Mb Multi-I/O SPI Flash
  • 10/100 Ethernet PHY
  • USB-to-UART port
  • On-board USB JTAG circuitry
  • Two 2x6 PMOD expansion ports
  • Single-chip, 3-rail power with Power Good indicator
  • Programmable clock chip
  • Over-voltage and ESD protection on USB
  • Four LEDs
  • 4-bit DIP switch
  • Reset and PROG push-buttons
It is going to be very interesting to see what we can make out of this small board with a really small price ($89). You are welcome to join me on this journey.

Spartan-6 FPGA Family

Spartan-6 FPGA delivers an optimal balance of low risk, low cost, and low power for cost-sensitive applications, now with 42% less power consumption and 12% increased performance. Spartan-6 FPGAs offer advanced power management technology, up to 150K logic cells, integrated PCI Express® blocks, advanced memory support, 250MHz DSP slices, and 3.2Gbps low-power transceivers (taken from Xilinx's datasheet).



We will us the LX version.

The development kit

We are lucky. Yesterday I attended the
FPGA World Conference in Stockholm. On the exhibition floor I met the Silica people who told me that they will run a Design Workshop featuring the low-cost Avnet Spartan-6 FPGA LX9 MicroBoard. After finishing the workshop I could buy the development kit for a bargain price ($59). Here it is.



The development kit includes:
  • Spartan-6 FPGA LX9 MicroBoard
  • USB A to micro-USB B cable
  • USB extension cable (Type A Male to Type A Female)
  • Xilinx ISE Design Suite 12.4 DVD
  • Documentation



Avnet Design Resource Center

Here is a link to the
Avnet support site. Click the Support Files and Downloads button at the bottom of this page to enter the Avnet Design Resource Center.




Here is a link to the
Avnet Technical Forums.






Pre-built MicroBlaze hardware platforms

To get started in the right direction, Avnet has generated and pre-built several MicroBlaze hardware platforms to use as our starting point. The platforms orignal XPS project is available as well as a version exported to SDK. Pre-built hardware platforms give hardware engineers a starting point for adding unique combinations of peripherals or even a custom-designed peripheral to off-load the CPU.

Pre-built hardware platforms are also an excellent starting point for software engineers as they can immediately begin using SDK and designing software applications. Here is one example there are many more.

Thanks debreuil for providing this picture.

Connecting the board to the host computer

We start by connecting the gray cable to the USB connector on the board. This cable will provide 5V to board and will also by used for programming the FPGA. When connecting this cable the green power good LED will light up.

The black cable connects to the mini-USB connector on the board and will provide a terminal connection.  When connecting this cable the amber USB link status LED will light up.


Connected



We are almost ready to go. Why not watch this video before we start.

Downloading and installing Xilinx Design Suite 13.2

We need some software from Xilinx. Here is an
instruction on how to install Design Suite 13.2

Recycling bin

These two items will go into the recycling bin. We don't need them anymore.

USB to JTAG converter



Serial IO to USB converter
