Could not find rtl_work.TB.vhd

Forget what we said, i've read on the datasheet i miss the library:

use work.FIXED_PKG.ALL

with it, the quartus works

but we are stuck at modelsim:

# ** Error: C:/Users/Alfonso/Desktop/PFC/fixed_pkg_c.vhdl(22): Library ieee_proposed not found.# ** Error: C:/Users/Alfonso/Desktop/PFC/fixed_pkg_c.vhdl(23): (vcom-1136) Unknown identifier "IEEE_PROPOSED".# ** Error: C:/Users/Alfonso/Desktop/PFC/fixed_pkg_c.vhdl(28): VHDL Compiler exiting

Repeat it to me over WHICH LIBRARY MUST I COMPILE, over work or over rtl_work

So:

vsim> vlib rtl_work

vsim> vmap rtl_work [pwd]/rtl_work

vsim> vcom -work rtl_work <your VHDL files>

or

vsim> vlib work

vsim> vmap work [pwd]/work

vsim> vcom -work work <your VHDL files>
