It is based on a Spartan 3 400, has a VGA port (which uses a real video DAC), RJ45, RS232, PS2, ..., and a PCI edge. It is a bit pricy for hobbyists like me ($399), but it seems to be a very well-thought through general-purpose dev board. Avnet also makes a version with a 1500 part for $100 more, though when I talked to them a month or so ago, they couldn't source the S3 1500 for production. If anybody has used this board and has some comments to share, please do! - NathanArticle: 71403

Does anyone know of a supplier of FPGA's in compact flash format? (Yes, I know of FPGA development boards that have slots for compact flash storage devices.) Compact Flash is a flexible standard that extends way beyond just flash storage devices. You can get GPS's, wireless LAN's, ADC/DAC's etc. etc. in Compact Flash format. What I want is to be able to plug an FPGA into my Sharp Zaurus PDA (which has a Compact Flash slot and embedded Linux) and use the PDA as the user interface to the FPGA.Article: 71405

This was wrong too. The Nios vector table entries are all right shifted addresses, so they look wrong in a memory dump. Function pointers will likewise be only half the value you expect. This plus the 5bit/11bit operations, the register windows, etc. all add to the chore of debug. tns1 wrote: > However, there is a bug in the way either my bootstrap or app gets > built, that causes the application to jump from sram to flash addresses > for any function call in main() (ISRs too).Article: 71409

What do you want the FPGA to do? FPGAs generally need to have their program loaded at power up time. That usually requires a few wires going in the back side. Where are you going to get them on your PDA? You could use a ROM on the CF card, but that removes a lot of flexibility. It might work if you know what you want the FPGA to do and don't want to change your mind very often.

Hi folks, I'm having a problem where I back-annotated the nodes of a LogicLock'ed SDRAM controller. The design was compiled with Auto Packed Registers = MINIMIZE on Quartus 3.0 SP1. When I recompile the design, it fails, sometimes with as little as 2 nodes not being able to fit. This problem does not occur if I compile Reg Packing = NORMAL, so I assume register packing is causing problems. I need to pack the registers to stay within the resource constraints of the project and I need to LogicLock to maintain timing. Is there a way to LogicLock a register-packed design and not have problems in subsequent compiles? -- PeteArticle: 71412

I have 5.1 ISE WebPACK running under wine but just discivered it doesn't support Spartan3. From the archives I read about some difficulties regarding 6.2 ISE running on wine, have these been solved? http://www.fpga-faq.com/archives/70825.html I urgently need to know if 6.2 ISE works under wine as I have just ordered the $99 Spartan-3 Starter Kit. If not I shall need to cancel my order. For those who haven't seen the Spartan 3 Kit: http://www.xilinx.com/products/spartan3/s3boards.htm Looks like a superb bit of kit, I will be buying a number of these for my University module. Having the RAM on board is great. The applications I have already thought about - add an ADC and you have a digital storage scope, Turbo decoder, LDPC codes and so on. We'll need to get the ISE 6.2 WebPACK running on Linux and write our own programmer software. Does anyone know of any Linux JTAG programming software suitable for the Spartan? Or details of the protocol for programming the FPGA? I guess I don't need to know the details of the bitstream, but I need to know how the bitstream is inserted into the JTAG data. At the moment my biggest hurdle (after learning VHDL!) will be getting 6.2 WebPACK running on wine. Regards AndrewArticle: 71414

First, Wine should be configured for a Version of "win2k". You also should get a copy of a native version of msvcrt.dll somewhere, and configure Wine to use it. If you are already running a previous version of Webpack under Wine, then I would guess you already meet those requirements. When installing Webpack, you will get some error dialogs, and some Wine processes will even crash. Don't worry, Webpack is still installed ok ;) Really! Finally, the biggest problem is that the GUI runs really slow with a current Wine, due to a named pipes bug. But this is also the same as in Webpack 5.1, so there will be no change here. If you are just using the command line tools, then they run fine. You could patch a version of Wine to run the GUI if you wanted; I have a patched version around that runs the GUI fine. -- My real email is akamail.com@dclark (or something like that).Article: 71415

The shortcut from doing 2's compliment is to invert the bits after the first 1 starting from the right. So for example: 10011100 (original value) VVVVV^The first 1 from the right 01100100 (2's compliment) Thus you can create an chain of 'or' gates connected to 'xor' gates to invert the bits after the first 1 bit starting from the right. It is possible to do this work in parallel but without implementing it, I don't know if it will actually be faster than a straightforward addition since most FPGAs have fast ripple-carry adders.Article: 71416

Just stay away from the musty stuff of the previous century ! Is there anyone working on a museum of FPGA history? While I agree that they don't have any practical value for current designs, they may have historical value.

So, I have a 32-bit processor design which I'd like to move to the
implementation stage, and I was wondering which of the
currently-available boards have 32-bit wide memory... I don't really
fancy designing my own because I've never ventured near 4-layer boards,
and if I was making my own, I'd want one of the FG456 packages, and
presumably you'd have to get that professionally soldered anyway...
As far as I can tell:
Xilinx starter kit
------------------
Pros: 32-bit wide RAM
LCD/Leds for debugging
PS2/VGA outputs
Price: $99 :-)
Cons:
Only 1 MByte of RAM
Uses the '200 part not the '400
No ethernet PHY
Fixed oscillator freq. (the CPU goes faster :-)
Not many user-IO's available
AVnet Spartan-3 evaluation kit
------------------------------
Pros: '400 part used :-)
Two oscillators, socketed
Lots of IO's available
Ethernet, VGA, PS2, RS232, Leds etc.
Could potentially be a PCI card
Cons: Only 1 MByte RAM
Not clear if the memory is 32-bit wide
Price is $399
Memec DS-KIT-3SLC400-PAC
------------------------
Cons: Has no memory on-board, enough said.
Nu Horizons Spartan3 board
--------------------------
Pros: Uses the '400 part, but only in the '208 package
Has D2A and A2D onboard
Has Flash RAM
Has LCD (4x24) as well as leds,buttons etc.
Has spare oscillator socket for > 20MHz operation
Price - $164 :-)
Cons: SDRAM appears to be 16-bit wide
Only has ~20 user io due to '208 package
So, nothing is perfect [grin], The AVNet one may be the best of the
bunch, despite being the most expensive, so long as it has 32-bit wide
RAM. I'd really appreciate it if someone who already has the board could
tell me :-)
For the record (in case any board companies are listening :-) my ideal
board would be something like:
- FG456 Spartan 3 '400 part
- Lots of user-IO, some with pin headers not obscure connectors
- 32+ bit wide RAM, either SRAM or SDRAM. How about a DIMM :-)
- Ethernet PHY
- Leds / buttons / LED (or LCD) display
- VGA and PS2 connectors
- PCI edge connector would be nice but not essential
If Xilinx can do theirs for $99, I think the above could be do-able for
$200 (or $199 in marketing speak). I'd bite your hand off :-)
