Split projects according to previous commit.  This project revision
compiles the hardware design to bitstream, but lacks controlling
software.  Still need to investigate potential damage risks indicated in
bitgen and synthesis warnings due to unconstrained hard macro pins in
the XADC IP core.  Finally, ring oscillators will be added with control
software to stress and calibrate the power distribution system and
thermal diode temperature to a corresponding ring oscillator frequency
value.
