Could not find rtl_work.TB.vhd

[Altera_Forum]

Hello,  

 The same process is giving issues once again: # ** 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   I remember to delete the work folder to be able to compile a library that need that according to a modelsim tutorial: http://doc.union.edu/118/se_tutor.pdf (http://doc.union.edu/118/se_tutor.pdf)   I have to do  vcom <vhdl files .vhd> # do this for all the files  cause it had to be done in the work folder, this may have caused the issue.   i'm lost, can anyone help me?.

--- Quote Start ---   use work.FIXED_PKG.ALL  with it, the quartus works   --- Quote End ---  Ok.   But this line means that you have changed back to the case where all libraries should be compiled into the work library.    --- Quote Start ---   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   --- Quote End ---  Read the error message - its telling you that its looking for library ieee_proposed. Doesn't that make you think:  oh, i thought i edited that file and changed those lines to use work.fixed_pkg.all;  Then you would edit the file, re-run the example and not have an issue. Try that, and let me know how it goes.  Cheers, Dave

--- Quote Start ---  Hello, i'm here again how do I save the results?  --- Quote End ---  This question does not make any sense.  Save what results?  From the error message you posted, the testbench rtl_work.tb_pfc_main cannot be found.   So have you added the testbench to the project? Look at the .do script and see if TB_PFC_main.vhd was ever compiled. If it was not, then you need to figure out how to include it.   I never use Quartus to launch Modelsim, so I'm not sure what you need to do for that step. You will need to read the Quartus documentation.  Cheers, Dave

Well, how do you launch modelsim, i'll do on your way, please help me.

--- Quote Start ---  Well, how do you launch modelsim, i'll do on your way, please help me.  --- Quote End ---    You can launch Modelsim from the Start Menu. It will be in the folder with your Quartus install.  Once its started do the following;  cd C:/Users/Alfonso/Desktop/PFC source PFC_run_msim_rtl_vhdl.do  and that will run (source) your script.  If that results in an error, post the messages from the Modelsim console.  Cheers, Dave

Hello,  

 same error:  # vsim -l altera -l lpm -l sgate -l altera_mf -l altera_lnsim -l cycloneii -l rtl_work -l work -voptargs=\"+acc\" -t 1ps tb_pfc_main # ** error: (vsim-3170) could not find 'c:\users\alfonso\desktop\pfc\simulation\modelsim\rtl_work.tb_pfc_main'.  but slighty diferent, my .do is not on the VHDL's root, its here:  C:\Users\Alfonso\Desktop\PFC\simulation\modelsim  but the procedure was the same:  cd c:/users/alfonso/desktop/pfc/simulation/modelsim source pfc_run_msim_rtl_vhdl.do  Alfonso,

Try removing -L rtl_work from the command line argument. 

 Your script creates a folder named rtl_work, and then maps it to the VHDL library work. There is no library named rtl_work, so it should not be listed with the -L option.  Alternatively,  vsim -t ps TB_PFC_main  should also work. Modelsim is pretty good about locating VHDL libraries.  Cheers, Dave

Sorrry sorry i know the cause of the problem. the top level entity testbench name was incorrect. 

 sorry, don't kill me even i deserve, cause i'm the stupiest in the world.

The nice thing about scripts is you can write comments in them to remind yourself why you did things. Using the GUI is not as useful, as if you do not use the tools for a while, you forget how to use it. Look at the modelsim_example.zip file I referred you to earlier, and look at this tutorial:  http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial  It has both Quartus and Modelsim Tcl scripts.  Cheers, Dave

Thank you Thank you thank you Dave, you are the only one has helped me to the end, the only fact that you are not left alone, helps going on, it's unbelievable the grateful i am, if i am fast i can this weekend teat all my testbench & project and monday/tuesday/friday show it to my master teacher to make all conclusions and finish the project. 

 Thank you for your involvement.

So i'll keep visiting this forum surelly, and here i know there are kind persons to ask to in case of complicated doubts.  Thank you!!!! See you.

For example, in the files you sent me yesterday, there were warnings about uninitialized variables and signals missing from process statements. Read each warning, and edit your code to clear the error. Clearing as many trivial syntax errors as possible will help you see the real problems.  Cheers, Dave

If you referd to "change the library those two packages are compiled into, eg., right click on the files, and set the library to rtl_work" -> work
