Papilio Playground

The playground is an area where anyone can contribute code, examples, documentation, or just pictures of the Papilio in action. Anything Papilio or FPGA related is welcome.

The playground is a publicly editable wiki and we encourage anyone to add or edit content, the password is "gadget". To edit any page scroll to the very bottom of the page and select "Edit Page". There are instructions for wiki markup at the bottom. The password to upload images is also "gadget".

FPGA Projects

Recommended reading for getting started with VHDL.

These books are targeted for "Synthesis" of VHDL on physical hardware instead of VHDL for simulation. It is important to make sure you are learning VHDL for Synthesis otherwise it gets confusing. These books have been reported as the "breakthrough" books that helped people get over the initial learning curve.

  • FPGA Prototyping by VHDL Examples: Xilinx Spartan-3 Version
  • FPGA Prototyping by Verilog Examples: Xilinx Spartan-3 Version
  • Essential VHDL: RTL Synthesis Done Right
