# Xs  appear as RED lines in the ModelSim waveform
#     diagrams. They frequently mean that a signal's
#     value can't be resolved because >= 2 values
#     are being assigned to it simultaneously.
#    
# Us  are also RED, indicating that no values are
#     being assigned to a signal#
# Zs  are BLUE
