- Dave Vandenbout wrote the original C++ version of XSTOOLs and the majority of the Python version.
- John Bowman wrote a Python version of xsload. Hector Peraza modified the python code to eliminate some problems and make FPGA configuration via JTAG conform to accepted practice. Dave took ideas and bits from Hector’s code and integrated them into this package.
- Al Neissner wrote a Python version of xsusbprg and bits of his code are used in this package.
- Alireza Moini added the methods for reading voltages from the XuLA board analog I/O pins. Dave modified these to output floating-point values.
