FPGA Workshop
From HacDC Wiki
Main Topics
1) Introduction to digital logic & design
2) Verilog HDL modeling & testing
3) FPGA's & using them.
We will be taking an approach of reviewing & learning digital design, implementing designs and methods of formally simulating and verifying designs before moving into FPGA oriented work. This will be a more engineering than hobbyist oriented workshop.
Hardware
We'll be covering some FPGA specific topics and projects using real hardware. The first half of the workshop will cover logic design, implementation and testing. This will allow people to put off ordering any hardware until they know that they actually want to pursue FPGA development, since the dev board I've chosen for this is not cheap but I feel is robust enough to be a good starting board for this group.
The hardware we'll be using is the Xilinx Spartan 3AN development kit. This kit is available from a few vendors for 199USD + shipping. This will be discussed more later on. The kit includes programming cable, and evaluation copies of some of the Xilinx tools."
Tools
Verilog Simulation and Waveform Viewing
Icarus verilog & gtkwave; for doing Verilog compilation, simulation and waveform viewing. A makefile has been made to simplify the flow for any exercises and projects we use these tools with. That makefile can be found here.
FPGA Toolchain
After we finish up with covering Verilog modeling, we'll move to the Xilinx ISE Webpack tools and actual work with FPGAs. This software is available from Xilinx for free, and is available for Windows and Linux platforms. This will be used for Verilog compilation, simulation, synthesis of designs, design mapping, place and routing of designs, bitstream generation and board programming.
Virtual Machine
An OpenSuse Virtual Machine (VMWare based) will be available for people to use in this course, if they wish. This will
have the icarus verilog tools and GTKwave loaded on it, along with Firefox and OpenOffice. The suseStudio team has encouraged the use of their VMs in such a manner (teaching workshops). This is being built in susestudio, and will be available as a live install as well.
When we move over to the Xilinx tools, people will have to download and install the Xilinx tools by themselves, since that material is copyrighted. Instructions will be given for doing that.
Lecture
Lecture/Discussions will mainly be based on content from a pair of courses in MIT's Opencourseware initiative. This content is licensed on the Creative Commons Attribution NonCommercial Share-alike 3.0 license; as a result, the electronic content generated by the workshop will also need to be made available under the same license.
A video archive will be made available for those unable to attend.
