Re: [Xylo-SDR] FPGA pin names in schematic
Thanks for the info. I have already been out to their site
looking. This board really has a lot of capability. This sounds like a
really good deal for $99. Don't see how I can hardly pass this up

You didn't find it because I misspelled the company name, it's
Digilent Inc., sorry about that, below is a link to the company. They make the
boards for Xilinx and Xilinx has a real nice deal on development
Your get two boards with this offer for $99 from
The chip is made by Xilinx and is a superior chip to the one used
in the Xylo board
You get a Spartan 3 200K development board, it has the following
200K logic cells.
500 MHz internal logic speed.
50 MHz clock
module built in
12 high speed multipliers built in.
1/4 meg bits internal
1MB of high speed external RAM, that can be accessed as 8, 16 or 32 bit
10 ns memory.
4 seven segment displays.
8 individual LED's
1 Optional extra clock module socket.
3 40 pin
connector for use in connecting to outside devices or boards, boards are
available from Digilent.
1 RS-232 Port
1 VGA video port
serial programming and JTAG connectors
get a CPLD development board for the $99 deal with two different CPLD chips on
it. A high capacity Cool Runner II chip with 256 cells and a XC9572 chip
You also get JTAG cables, power supply, CD with development
software, and CD's full of tutorials, and sample projects.
The CPLD board
can connect to the Spartan 3 directly, or to another device via a cable to
be a smart I/O board. The CPLD board has a large breadboard area on it.
real good deal for $99
You can get plug in boards and devices from the
following folks, such as Ethernet, USB, A/D converters, DAC's, motor drivers,

Digilent are the
people who make these boards for Xylinx so they have special versions available,
but you do not get the CPLD development board. The Spartan 3 board I bought uses
the 1000K chip instead of the 200K, it has guess what, 5X the logic resources.
It also has 2X multipliers, 2X internal RAM. I will be using it for developing
CPU's and DSP engines, which is a interest of mine, it cost $150.
The only problem and it's a minor one, is that is made by Xilinx not
Altera, most people on the group use Altera so they are not using the same
software that comes with the kit. However the software are somewhat similar, and
both chips and development software use the same languages to program the chip,
HDL, VHDL, and Verilog and those languages are supported by both development
Hope I didn't overload you with too much

ask, where did you aquire the Diligent Spartan3 dev board? Googling didn't
produce anything useful.
