ModelSim Altera Edition version 10.0c
 
This readme.txt file for the ModelSim(tm) Altera Edition software 
includes information that was not incorporated in the printed 
documentation or online help. 
This file contains the following sections:

* Quartus II Version Compatibility 
* New features in ModelSim-Altera 10.0c
* VHDL 87/93/2002 Compatibility
* Installation & Licensing 
* Potential Problems & Recommendations 


Quartus II Version Compatibility
================================

It is critical that the compiled libraries provided in the 
<modelsim install path>/altera directory be compatible with 
version of Quartus II that is used to create the simulation 
netlist. To ensure that you have the right version of libraries 
installed, you can use either of the following methods:

1.  Check the <modelsim install path>/altera/version.txt file
2.  Perform the following steps:

        cd <modelsim install path>/altera
        <modelsim install path>/win32aloem/vdir -l -lib <library name> 
        where <library name> = stratixii, cycloneii,..etc.
        Check for Quartus II version in 'Library Version' tags

New features in ModelSim-Altera 10.0c
====================================
ModelSim-Altera 6.6c and later versions add a new feature called the "Waveform editor" that can be used to
create stimulus, run simulation, and generate HDL testbenches.
For more information refer to Chapter 12 (Generating Stimulus with Waveform
Editor) in ModelSim User's Manual.



VHDL87/93/2002 Compatibility
============================
The default VHDL support in ModelSim-Altera 10.0c is VHDL-2002. 
Compiling with the -93 option disables the support for VHDL-1987 
and VHDL-2002. Compiling with the -87 option disables the support 
for VHDL-1993 and VHDL-2002.

Potential Problems & Recommendations 
====================================

1. You may get the following errors when loading projects created
   using previous versions of ModelSim-Altera in ModelSim-Altera 10.0c

# ** Error: (vsim-3193) Load of "<modelsim-altera_install_dir>\win32aloem/../win32aloem/convert_hex2ver.dll" failed: File not found.

# ** Error: (vsim-PLI-3002) Failed to load PLI object file "<modelsim-altera_install_dir>\win32aloem/../win32aloem/convert_hex2ver.dll".

  You should remove the modelsim.ini located in your design directory
  to resolve this issue. Alternately, you can edit the file modelsim.ini
  and remove the line

Veriuser = $MODEL_TECH/../win32aloem/convert_hex2ver.dll
