Open JTAG Project is an open source hardware and software for a high speed USB JTAG tool.
In this site, you can find and download all necesary files to make your JTAG device. The electric schematics, the PCB design including Gerber files, the VHDL project in Altera Quartus II format, and the C++ examples in Microsoft Visual Studio 2005, are free to be downloaded. If you like to collaborate, please click on our Opencores.org Open JTAG project page.
We encourage JTAG lovers to collaborate with this project:
- Patch the OpenOCD to support Open JTAG commands.
- Optimize the VHDL code (I am not the best VHDL programmer, of course!)
- Test hardware and software
