Computer Architecture Simulation Models

DOWNLOADING, INSTALLING & USING HASE

1. to be able to run HASE
2. to have your own copy of the model files

(† Users at the School of Informatics, University of Edinburgh, do not need to download HASE; it is publicly available at /group/project/public-hase/HASE-III/Hase).

REQUIREMENTS

• System Requirements:
  • Java 1.5
  • GCC V3.x.x.x or higher
  • libstdc++.so.6
    • Linux: Fedora Core 3 or later
    • Windows: cygwin
• Symbolic Link Requirements:
  • To check that a symbolic link exists to java, use:   java -version
    the result should be:   java version "1.5.x.x"
  • To check that a symbolic link exists to GCC, use:   g++ --version
    the result should be:   g++ (GCC) 3.x.x.xxxxxxxxx (OS information)
  If either of these links does not exist, but the required versions of Java and GCC are installed on your system, then before continuing, make links to them using the `alias' command in your .brc file, or by setting symbolic links.

INSTALLATION

• Download Setup_HASE_III_1.2.1.2.jar into an appropriate directory
• Enter this directory:
  cd /Directory_Containing_Setup_HASE_III_1.2.1.2.jar/
• If you have root access:
  • Enable root access:
    su
    Password:xxxxxxx
  • Run the installer:   java -jar Setup_HASE_III_1.2.1.2.jar
  • Follow the installer instructions, selecting `Install for Everyone' on the option page.
  • Check that the installer has selected the right operating system
• If you do not have root access:
  • Run the installer:   java -jar Setup_HASE_III_1.2.1.2.jar
  • Follow the installer instructions, selecting Select `Install for Just Me' in the installation options. Make sure you choose an appropriate installation directory (e.g. not /opt in MAC OS X). After the installer finishes in this mode, you will have to make your own aliases to /HaseInstallDirectory/bin/Hase to be able to run Hase

MODEL FILES

This will create a subdirectory for the model containing all the files needed to create your own version.

RUNNING HASE

HASE-III will default its open dialog box to the directory from which it is run.

To use the model, move to the subdirectory/folder for the model and start up HASE. The file menu or the left most icon in the HASE window can be used to open a selection window and the project is loaded by selecting <model_name>.edl. Then compile the project using the Build Project option in the Project menu (or the build icon).

To run the simulation, use the Simulate option in the Project menu (or the run icon). During the simulation, HASE writes a trace file into a Results subdirectory (model_name.sim). When the simulation stops, load the trace file using the Load Trace File option in the Project menu (or the clock icon). When the tracefile is loaded, the animation buttons will light up. Using these buttons you can play the animation, stop it, single step it, re-wind it, etc.

Selecting the parameters tab in the Project Inspector panel allows changes in the values of entity parameters to be observed during simulation. These include register and memory contents, for example. The parameter display of each entity can dragged out of the main display into a separate window either by clicking on the hatched area at the left of by left clicking on the entity's icon whilst holding down the shift key (though the latter option is currently unavailable on MACs). If the window is closed, it re-docks with the main display.

DOCUMENTATION

DISCLAIMERS, ETC

1. The Help facility is still under construction; the Hase++ section in particular is incomplete.
2. There are still a few bugs in the HASE code (e.g. using the Help facility can sometimes throw java errors - just close HASE and start again).
3. Some files for some of the models contain some redundant code left over from development.
4. In case of difficulties, please send email to icsa-sec@inf.ed.ac.uk and we'll try to help.
