Re: Official Open Source FPGA Bitcoin Miner (Spartan-6 Now Tops Performance per $!)
The teknohog xilinx-verilog port also works good with the Xilinx Spartan 6 LX45T eval board called "SP605".
The only trick is that TX and RX in the SiLabs USB-RS232 adapter is reversed so you need to swap the pins in the UCF file to make a null modem.
After finding 7 blocks I have a hash rate of 13.1 +-4.95 with a clock speed of 63MHz and unrolling = 3.
I'm not saying these boards are useful for any real life mining but if you need a working reference example this does the job.
You can test run these devices with the xilinx ISE webpack license (which reports some stats back to xilinx but has a $0 cost). The only thing you risk is a salesguy calling you and asking when you will be purchasing volume..
Good luck, have fun!
