Installation Guide

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 and unpack the MicroTESK installation package (the .tar.gz file, latest release) to your computer.
  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. [Optional] Set the <installation dir>/bin as the working directory (add the path to the PATH environment variable).
  5. Now you can run the (or .bat) script to create a microprocessor model and the (or .bat) script to generate test for this model.

Setting Environment Variables


  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 <instrallation 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 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 ( 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:, unpack the archive and place the z3.exe file to the <installation dir>/tools/z3/windows directory.

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

Running MicroTESK

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

sh ../arch/mips/model/mips.nml

To generate a test program, a user needs to use the script (Unix, Linux, OS X) or the generate.bat script (Windows). The scripts require the following parameters: (1) model name , (2) test template file and (3) target test program source code file. For example, the following command runs the mips_demo.rb test template for the MIPS model generated by the command from the previous example and saves the generated test program to the test.asm file:

sh mips ../arch/mips/templates/mips_demo.rb test.asm
