VHDL Package not detected by Modelsim

[ZKhan1]

Hi all ,

I am using Quartus Prime ver 16.0 for compilation of my vhdl project files , the project compiles fine without any errors , but when i start simulation the Modelsim cantt seem to find my package file .

Modelsim version : ModelSim ALTERA STARTER EDITION 10.4d

Although i made a "work" folder myself and pasted the vhdl package in it , but still no effect , then i copied the folder and pasted it in D:\Quartus_projects\i2c_audio_Fir_filtr1p1\simulation\modelsim

 Still i get this error :

In my Top vhdl file and in my testbench i have declared it like this :

LIBRARY ieee;
USE ieee.std_logic_1164.ALL;
-- USE IEEE.std_logic_arith.ALL;
USE ieee.std_logic_unsigned.all;
USE ieee.numeric_std.ALL;
use ieee.math_real.all;
USE std.textio.ALL;

Library work;
use work.audio_codec_i2c_pkg.all;

Any clue why modelsim is not able to open it ???

Spelling difference?  audio_codec_i2c_pkg vs. audio_codeci2c_pkg

Thanks i got rid of that error , but now i am getting this error :

Can you show the code lines from the file that are mentioned as having issues?

[BikshuNaik]

I have generated some IPs in Quartus Prime Pro edition software and due to some reason I am trying to simulate the design in Modelsim -INTEL FPGA Starter edition and I am facing errors like this:

** Error: (vsim-3033) ../.../IP_Folder/pll_div_by2/altera_iopll_1931/sim/stratix10_altera_iopll.v(498): Instantiation of 'fourteennm_iopll' failed. The design unit was not found.

** Error (suppressible): (vsim-19) Failed to access library 'fourteennm_ver' at "fourteennm_ver".
# No such file or directory. (errno = ENOENT).

so can someone please help me? what is my mistake and how to solve this.

I'm guessing the simulator doesn't like your use of "us" and "ms" right after a value without a space.

[ZKhan1]

Thanks again for pointing that out , i did get rid of those warnings , but i still get that error :

[ZKhan1]

With in Modelsim in the above attached pic , i noticed that Modelsim only has "Fir_left_ch" , although in vhdl top file i have two Fir ip included one for left and other for right channel .  Anyway i right clicked on the tb in the work folder and forced compiled it , and it successfully compiled it and then simulated the tb and it worked .  

[ZKhan1]

I still want to get rid of this annoying error which pops up when i start simulating from Quartus i.e "# ** Error: (vsim-19) Failed to access library 'tb_audio_ctrl_Top' at "tb_audio_ctrl_Top". 

Why do i have to force compile and simulate the tb

Ahmed,

You probably need to look at below KDB related to your issue

Ahmed,

Let me know if there is any update or concern on this

Hi Ahmed,

Are you managed to work on this issue? Is the KDB applicable at your end?

Let me know any update.

[ZKhan1]

HI ,

I havent been able to resolve this issue the "verror 19" refers to "modeslim.ini" file , but this file is generated by Modelsim-altera , and dont see any variable that is uncorrectly set in it ???

What is KDB ?

Ahmed,

What is KDB ?

The Intel® FPGA Knowledge Base page provides links to applicable articles that span a variety of FPGA related issues. You may refer to link below for more KDB

You probably need to reinstall Modelsim and see if it can detect vhdl package for you simulation 

[ZKhan1]

Hi ,

I dont think reinstalling Modelsim can solve the issue , as it is working fine for other projects , the mapping to libraries is perfect .

This modelsim.ini file has be generated again .

Regards ,
