Has anyone used the Digilent Digilab 2E development board sold through NuHorizons? How about its predecessor, Digilab 2? Any opinions on their boards? I want to design with the Spartan-IIE series and something with 100k-200k gates. It appears all the I/O pins are accessbible through 100mil pin spaced headers. I want to implement 8bit cpu, custom datastream decoder, about dozen push buttons, SDRAM interface (8MB), possibly a CF card interface (ATA), and I2C bus. I realize this will take me some time, a lot of time to implement. My guess is that the 200k gates will likely be able to implement all my needs minus the ATA interface. http://www.nuhorizons.com/services/development/Xilinx/SpartanIIE/SpartanIIEBoard.html http://www.digilentinc.com/Products/products.html Digilab 2E - XC2S200E FPGA - parallel port - serial port - jtag port Suprisingly the Digilab 2E does not appear on Gigilentinc's webpage. |
