MicroTESK

h1. Installation Guide

{{toc}}

h3. System Requirements

MicroTESK is a set of Java-based utilities that are run from the command line. It can be used on *_Windows_*, *_Linux_* and *_OS X_* machines that have *_JDK 1.7 or later_* installed. To build MicroTESK from source code or to build generated Java models, *_Apache Ant version 1.8_ or later* is required. To generate test data based on constraints, MicroTESK needs *_Microsoft Research Z3_* that can work under the corresponding operating system.

h3. Installation Steps

# Download from http://forge.ispras.ru/projects/microtesk/files and unpack the MicroTESK installation package (the @.tar.gz@ file, latest release) to your computer. The folder to which it was unpacked will be further referred to as the installation directory (@<installation dir>@).

# [Not required for MicroTESK 2.1 beta] Download and install constraint solver tools to the @<installation dir>/tools@ directory (see the *Installing Constraint Solvers* section).

# Declare the *MICROTESK_HOME* environment variable and set its value to the path to the installation directory (see the *Setting Environment Variables* section).

# Set the @<installation dir>/bin@ as the working directory (add the path to the @PATH@ environment variable) to be able to run MicroTESK utilities from any path.

# Now you can run the @compile.sh@ (or @.bat@) script to create a microprocessor model and the @generate.sh@ (or @.bat@) script to generate test for this model.

h3. Setting Environment Variables

h4. _Windows_

# Open the "System Properties" window.

# Switch to the "Advanced" tab.

# Click on Environment Variables.

# Click "New.." under "System Variables".

# In the "New System Variable" dialog specify variable name as @MICROTESK_HOME@ and variable value as @<installation dir>@.

# Click "OK" on all open windows.

# Reopen the command prompt window.

h4. _Linux and OS X_

Add the command below to the @~.bash_profile@ file (Linux) or the @~/.profile@ file (OS X):

<pre>export MICROTESK_HOME=<installation dir></pre> To start editing the file, type @vi ~/.bash_profile@ (or @vi ~/.profile@). Changes will be applied after restarting the command-line terminal or reboot. You can also execute the command in your command-line terminal to make temporary changes.

h3. Installing Constraint Solvers

To generate test data based on constraints, MicroTESK requires external constraint solvers. The current version supports the "Z3":https://github.com/z3prover and "CVC4":http://cvc4.cs.nyu.edu constraint solvers. Constraint executables should be downloaded and placed to the @<installation dir>/tools@ directory.

*_Installing Z3_*

* Windows users should download Z3 (32 or 64-bit version) from the following page: http://z3.codeplex.com/releases and unpack the archive to the @<installation dir>/tools/z3/windows@ directory. Note: the executable file path is @<windows>/z3/bin/z3.exe@.

* UNIX and Linux users should use one of the links below and and unpack the archive to the @<installation dir>/tools/z3/unix@ directory. Note: the executable file path is @<unix>/z3/bin/z3@.

| Debian  x64 | http://z3.codeplex.com/releases/view/101916 |

| Ubuntu  x86 | http://z3.codeplex.com/releases/view/101913 |

| Ubuntu  x64 | http://z3.codeplex.com/releases/view/101911 |

| FreeBSD x64 | http://z3.codeplex.com/releases/view/101907 |

* OS X users should download Z3 from http://z3.codeplex.com/releases/view/101918 and unpack the archive to the @<installation dir>/z3/osx@ directory. Note: the executable file path is @<osx>/z3/bin/z3@.

*_Installing CVC4_*

* Windows users should download the latest version of CVC4 binary from http://cvc4.cs.nyu.edu/builds/win32-opt/ and save it to the @<installation dir>/tools/cvc4/windows@ directory as @cvc4.exe@.

* UNIX and Linux. _TODO_

* OS X. _TODO_

h3. Installation Directory Structure

The MicroTESK installation directory contains the following subdirectories:

| @arch@   | Examples of microprocessor specifications and test templates for the described designs |

| @bin@    | Scripts to run features of MicroTESK (modelling and test generation) |

| @doc@    | Documentation on MicroTESK |

| @gen@    | Generated Java models of the specified microprocessor designs |

| @lib@    | JAR files and Ruby scripts to perform modelling and test generation tasks |

| @src@    | Source code of MicroTESK |

h3. Running MicroTESK

To generate a Java model of a microprocessor from its nML specification, a user needs to run the compile.sh script (Unix, Linux, OS X) or the compile.bat script (Windows). For example, the following command generates a model for the miniMIPS specification:

<pre>

sh bin/compile.sh arch/minimips/model/minimips.nml

</pre>

_NOTE: Models for all demo specifications are already built and included in the MicroTESK distribution package. So a user can start working with MicroTESK from generating test programs for these models._

To generate a test program, a user needs to use the generate.sh script (Unix, Linux, OS X) or the generate.bat script (Windows). The scripts require the following parameters: 

#  _model name_;

# _test template file_;

# _target test program source code file_.

For example, the following command runs the @euclid.rb@ test template for the miniMIPS model generated by the command from the previous example and saves the generated test program to the @test.asm@ file:

<pre>

sh bin/generate.sh minimips arch/minimips/templates/euclid.rb test.asm

</pre>
