Could not find rtl_work.TB.vhd

--- Quote Start ---

but if i close the modelsim and launch it (even having compiled again) reappears the error:

# ** error: (vsim-3170) could not find 'c:\users\alfonso\desktop\pfc\simulation\modelsim\ rtl_work.tb_pfc_main'.# Error loading design# Error: Error loading design # Pausing macro execution # MACRO ./PFC_run_msim_rtl_vhdl.do PAUSED at line 34

But here you are doing something completely different - you are running a Tcl scope called PFC_run_msim_rtl_vhdl.do

If you want to use the fixed-point package and use that Tcl script, you need to read the script to determine how it configures the library mappings. Most likely you can just add the lines to compile the fixed-package into rtl_work into that Tcl script.
