Using FPGA

Warning: There is a bug with ISE-13.x and upper, when tcl script is launched, the constraints file (ucf) is not read and ISE choose FPGA pinout randomly. To avoid this problem, once the script is sourced, re-launch the entire process by clicking right on «Generate Programming File» once and selecting «re-run all»

Developing on the APF FPGA

1. Starting Up with FPGA All you need to know to play with the Armadeus FPGA.	Design Tools Description of tools used to simulate, to synthesize, and to download/configure FGPA. ISE WebPack (Xilinx's free devt tool) installation How to setup the FPGA toolchain in Ubuntu/Debian How to simulate post synthesis and post place & route design with GHDL
2. Make some examples These examples give the basis to make VHDL design for FPGA. LED Complete example with button and led on wishbone bus communication and Linux drivers	Using Armadeus FPGA Manage the FPGA from Armadeus distribution. Configure or flash FPGA ? Configure the FPGA from Linux, from U-Boot Flashing FPGA firmware from Linux, from U-Boot Access the FPGA address domain from Linux Ho! No FPGA-reset button on armadeus card.
3. Automatize FPGA design making Peripherals On Demand For complex projects, POD should be used to simplify design.	VHDL VHDL coding styles & externals documentations Nice ideas/examples to look at www.opencores.org An Introductory VHDL Tutorial
