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.

Installation Steps¶

1. 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>).
2. [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).
3. Declare the MICROTESK_HOME environment variable and set its value to the path to the installation directory (see the Setting Environment Variables section).
4. 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.
5. 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.

Setting Environment Variables¶

Windows¶

1. Open the "System Properties" window.
2. Switch to the "Advanced" tab.
3. Click on Environment Variables.
4. Click "New.." under "System Variables".
5. In the "New System Variable" dialog specify variable name as MICROTESK_HOME and variable value as <installation dir>.
6. Click "OK" on all open windows.
7. Reopen the command prompt window.

Linux and OS X¶

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

export MICROTESK_HOME=<installation dir>

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.

Installing Constraint Solvers¶

NOTE: Not required for MicroTESK 2.1 beta.

To generate test data based on constraints, MicroTESK requires external constraint solver engines. The current version uses the Z3 constraint solver by Microsoft Research (http://z3.codeplex.com/). The Z3 executable should be downloaded and placed to the <installation dir>/tools directory.

• 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.

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

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:

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

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:

1. model name;
2. test template file;
3. 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:

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