Could not find rtl_work.TB.vhd

Please, can anyone help me?

The VHDL code is trying to use a component compiled into the rtl_work library. You can either compile your code into rtl_work via;

vsim> vlib rtl_work

vsim> vmap rtl_work [pwd]/rtl_work

vsim> vcom -work rtl_work <your VHDL files>

or you can simply map the rtl_work library to the same location as the work directory, eg., assuming you have created your work directory in the same folder you are working in via

vsim> vlib work

vsim> vmap work [pwd]/work

then you can tell Modelsim to look in the work directory for the rtl_work components too by mapping it via

vsim> vmap rtl_work [pwd]/work

(You don't need the [pwd] statement if you don't want to use absolute paths in your .ini or .mpf file).

Dave

Hello,

by typing this, how do you fill <your vhdl files>, by typing my vhdl files root (C:\Users\Alfonso\Desktop\PFC\altera) returns this:

(I typed vsim> vcom -work rtl_work C:\Users\Alfonso\Desktop\PFC\altera)

It did not work, assuming [pwd] is written as [pwd] litterally (if it is a root instead, tell me) after typing those three lines literally as you did it continues returning me:

# ** 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

Please help me i cannot test my code till this is solved.

You've passed it a directory, not a VHDL file. You need to pass the vcom command the files that end in .vhd. You need to compile all of your files into the work library. If you are using Modelsim-ASE, then you do not need to compile Altera libraries.

Cheers,

Dave

Thank you for the effort.

I typed:

...

vcom -work rtl_work fixed_float_types_c.vhdl

and it returned:

# Model Technology ModelSim ALTERA vcom 10.0c Compiler 2011.09 Sep 21 2011# ** Error: (vcom-7) Failed to open design unit file "fixed_float_types_c.vhdl" in read mode.# No such file or directory. (errno = ENOENT)# E:/altera/11.1sp2/modelsim_ase/win32aloem/vcom failed.

I moved from desktop to D: and tried again but failed with the same code, i try giving them write licence to all project files and folders, also with that failed.

Try reading the output from Modelsim - it says that it cannot find the file.

So where is fixed_float_types_c.vhdl located? If its not in the same directory as Modelsim is currently located, then you have to supply the full path to the file. For example, something like

vsim> cd c:/temp

vsim> vlib rtl_work

vsim> vmap rtl_work rtl_work

vsim> vcom -work rtl_work c:/vhdl/ieee_fixed_pkg/fixed_float_types_c.vhdl

Hello,

Seems all of this work, But:

when i copy fixed_pkg_c.vhdl & fixed_float_types_c.vhdl now everything goes ok!

vcom -work rtl_work fixed_float_types_c.vhdl# Model Technology ModelSim ALTERA vcom 10.0c Compiler 2011.09 Sep 21 2011# -- Loading package STANDARD# -- Compiling package fixed_float_types

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

how do i do to save the results??

To launch ok modelsim i've got to close the console and reestart the modelsim, wich takes me to # ** error: (vsim-3170) could not find 'c:\users\alfonso\desktop\pfc\simulation\modelsim\ rtl_work.tb_pfc_main'.

Thank you!!

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.

Cheers,

Dave

What's the TCl script??? , if i modify the PFC_run_msim_rtl_vhdl.do (Tcl scope) by adding:

vcom -work rtl_work fixed_float_types_c.vhdl

vcom -work rtl_work fixed_pkg_c.vhdl

It does overwrite and here we are again.

What have i to modify? (Tcl script) What's this?

If you do not know what a Tcl script is, then you need to go through some of the Modelsim documentation. Tcl = Tool Command Language, and its the language used to script (automate) the Quartus and Modelsim tools.
