Hello. I have a quick question, I am looking for the exact schematic for the "Digilent Spartan-3an Board". The Digilent part number is: PB210-112. I have the Revision D board, but I'd be happy to get anything "-3AN". The -3A board schematic is close, but there are many reference designator differences that make it difficult to follow the design and actual board. I've scoured the internet, but couldn't find this particular schematic. Can anyone help me locate it? Thank you, Richard V
Hello. I picked up this Spartan-3AN development board to follow along this good book: "FPGA Prototyping by VHDL Examples", Xilinx Spartan -3 Version, by Phong P. Chu. The book appears to be published by Wiley-Interscience. It's a very good book to learn VHDL with. Dr. Chu recommended using ISE version 8.2 and Modelsim XE III. I tried using the latest ISE version (14.7), but it kept crashing. What I would like to ask is, can you recommend a tool-chain that is still available, and is compatible with the Spartan 3 series boards? I am able to synthesize a project using ISE 8.2, but I can't program it with the IMPACT tool, per the book. The book describes how to perform the programming process using a "boundary scan" via the JTAG interface. I do not have the JTAG dongle, so I'm tyring to use the on-board USB programmer, but I can't find any information on how to use it. I saw one post mentioning a tool called "Adept", so I tried downloading it. It requires a "bash" tool to install it, so I gave on that. I would spend more time on it if I knew what is the correct tool-chain to use, given that this is an old outdated board with little support. Should I try to get the latest version of ISE working, or find the programming software to use that USB programmer? Another approach would be to buy a dongle, but I'm not sure which one to get. My JTAG interface is 2x6 pins. It looks like the same set of pins on each row, so I don't know if 1x6 interface will work. Digilent has 2 USB dongles, one is 14 pins (Jtag 2), and the other is 6 (Jtag 3). Each one is about $60, so I didn't want to just guess by buying that 1x6 (Jtag 3) programming dongle. It seems to me that the Type B USB cable connector was made for programming, but I don't know what software it will work with. The IMPACT tool keeps crashing when I try to communicate with my board. I can do synthesis and generate the bit file, but I can't program it. I also can't run the debugger. Could someone please make a suggestion to help extend the life of these excellent Spartan-3 boards? Thank you, Richard V
