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.

Xilinx

• ISE WebPack (Xilinx's free devt tool) installation
• Vivado installation on Linux
• How to setup the FPGA toolchain in Ubuntu/Debian
• How to simulate post synthesis and post place & route design with GHDL

Altera

• Quartus Web edition (Altera's free devt tool)
• Install Modelsim-Altera (starter edition)

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, from PCIe.
• Flashing FPGA firmware from Linux, from U-Boot
• Access the FPGA address domain from Linux

3. Automatize FPGA design making

Peripherals On Demand

For complex projects, POD should be used to simplify design.

Migen

With migen, it's possible to develop FPGA design in Python then generate Verilog for synthezis.

Chisel

With Chisel, it's possible to develop FPGA design in Scala then generate C++ model for simulation and Verliog model for synthezis.
