Could not find rtl_work.TB.vhd

C'mon man, stop jumping around tools :)

You earlier posted the script contents that contained:

vcom -93 -work work {C:/Users/Alfonso/Desktop/PFC/altera/fixed_float_types_c.vhdl}
vcom -93 -work work {C:/Users/Alfonso/Desktop/PFC/altera/fixed_pkg_c.vhdl}

These commands compile the packages into work for Modelsim.

Your above error is for Quartus. If you have the files added to your project, right click on them, and check they are being compiled into the work library. Make sure the package definitions are compiled prior to their use.

Cheers,

Dave
