Thanks to all who have posted here, I have read all of the helpful information pointed out on the Xilinx site. Very interesting, and has made me rethink my coding style significantly with regards to the reset signal.

I have seen warning messages from
Quartus synthesis will take advantage of registers which do not specify a power-up condition in don't care optimizations. Note that this can often result in registers being synthesized away because they are stuck-at in one power-up state, so it is important for designers to read the messages as warnings, not info. The assignment editor allows one to protect a register from this optimization, or specifically give a power-up value to a register or set of registers.
Hope this helps.
