I have Quartus Prime Lite Software with IP free license, when I implement the NCO IP in my design it shows up in the RTL View correctly connected up, but then when I go to Technology Map Viewer the NCO input and outputs are optimized out and all I get is a data strobe coming out of the NCO???
to debug I even set some of the ports to a constant and the NCO output still gets optimized out, meaning there is no output from my signal generator.

You may try with this in the qsf:
set_global_assignment -name PRE_MAPPING_RESYNTHESIS OFF
set_global_assignment -name REMOVE_REDUNDANT_LOGIC_CELLS OFF
set_global_assignment -name REMOVE_DUPLICATE_REGISTERS OFF
