From HacDC Wiki
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 workshop will be more engineering oriented than hobbyist/tinkerer oriented.
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."
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.
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.
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, gcc and make. 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/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. This will allow people to freely access just the discussion slides without watching through videos.
A video archive will be made available for those unable to attend.

This workshop will be free of charge to attend, but there are additional needs in order to fully benefit from attending the workshop.
- Open mind to learning
- Willingness to read documentation, as the capacity for independent research is important for doing hardware design.
- Willingness to commit time over this fall
- Either ability to run a VMWare virtual machine, the ability to convert the VM for virtualBox, or ability to install the icarus verilog/gtkwave tools on your own. This will likely necessitate a laptop of some sort.
- Xilinx.com account, for licensing Xilinx tools and IP.
- Hardware will NOT be required at the beginning of the course but will be needed later on to run exercises and to do any interesting projects
