The AAA Methodology and
HOME DOWNLOAD DOCUMENTATION COLLABORATIONS PUBLICATIONS SCICOS/SynDEx SynDEx-IC

From this area you can download:
  • the SynDEx software (last and previous versions for v8 and v7.X.X),
  • several executive kernels necessary to translate the executive files (macro-code) automatically generated by the SynDEx software into a source code (one executive file for each processor of your hardware architecture).

The SynDEx software

SynDEx 8 (alpha) is a textual version which does not provide a built-in interactive GUI. It includes significant changes but is not stable. Find out this new version!


SynDEx 7 is the stable version that includes new features (vs. version 6)

  • An improved code generation (v7.0.8)
  • Multi-periodic applications
  • Adequation based on multi-periodic distributed real-time scheduling analyses
  • Verification of dependence cycles even though hierarchy
  • New Graphical User Interface for algorithm specifications:
    • Single window grouping all the definition operations,
    • Abstract reference,
    • Superblock,
    • Undo: yes, we did it!
NB: SynDEx v6 files are compatible with SynDEx v7.

  • SynDEx v7.0.8 is released for Linux 64 bits
  • SynDEx v7.0.7 for Linux 32 bits
  • SynDEx v7.0.6 for Windows and Mac OS X

Changes

  • In SynDEx v7.0.8:
    • Code generation improved for conditioned and shared memory communications applications.
  • In SynDEx v7.0.7:
    • For multi-periodic applications:
      • do not keep copies of operations for the schedulability analysis,
      • solve computation errors on start dates,
      • fix a bug on basic mono-processor example (considered as not schedulable in v7.0.6),
      • implement a missing case (when no operation assigned on an operator),
      • improve schedulability messages (use of "The system is not schedulable" message only for non schedulable applications, and use of "SynDEx cannot find any schedule for this system" message otherwise),
      • improve user manual,
    • Grammar more explicit for the adequation result,
    • "Save Adequation with Application" option reactivated,
    • Fix a bug while consistency check of the application,
    • Fix the revision number in the GUI.
  • In SynDEx v7.0.6:
    • Fix of a bug in multi-periodic adequation resulting in missing 'wait' operations when the adequation result was not displayed,
    • Bug fix in code generation when dealing with delays and shared memories,
    • Minor fixes.
  • In SynDEx v7.0.5:
    • Bug fix in reading precedence edges from .sdx files,
    • Bug fix in code generation when dealing with shared memories,
    • New 'auto-position' button in algorithm window,
    • Minor fixes.
  • In SynDEx v7.0.4:
    • Improvements of error/warning messages,
    • Minor fixes,
    • Addition of the reference manual to the distribution; this manual can be open, as other manuals, from the help menu of the main window.
  • In SynDEx v7.0.3:
    • Various bug fixes on multi-periodic support,
    • Improvements of error/warning messages,
    • Addition of missing files in the distribution.
  • In SynDEx v7.0.2:
    • Bug corrections:
      • Error "cannot open file" when "open file" removed,
      • Error "Not_found" when modification of duration during adequation removed,
      • Flattening improvement,
    • New refresh button in algorithm window,
    • More information about multi-periodic applications in the user manual.

Pre-requisites

Tcl/Tk 8.4 is required to run SynDEx:

  • For Linux:

  • For Windows:
      Use the ActiveTcl distribution which can be downloaded freely from www.activestate.com. Install the most recent 8.4 version for Windows (x86) even if you have a Windows (x64). Please note that if you have a Tcl/Tk version higher than 8.4, running SynDEx might fail. Renaming the dll should solve the problem.

  • For Mac OS X:
      You can install the ActiveTcl distribution which can be downloaded freely from www.activestate.com. Install the most recent 8.4 version for Mac OS X (Universal). Then before running SynDEx you'll have to change your DYLD_LIBRARY_PATH variable to use this Tcl/Tk instead of the default one installed in /System/Library. In the terminal, use the following command:
      export DYLD_LIBRARY_PATH=/Library/Frameworks/Tcl.framework:/Library/Frameworks/Tk.framework:$DYLD_LIBRARY_PATH
      Please note that if you have a Tcl/Tk version higher than 8.4, running SynDEx might fail. Creating a symbolic link to the 8.4 version of the library should solve the problem.

Download

SynDEx v7 runs under Linux, Windows, Mac OS X platforms:

Previous releases are available here.

Installation

Uncompress and extract the downloaded archive:

  • Under Windows, use WinRar.
  • Under Linux and Mac OS X, use the command:
    tar -xvzf syndex-7.0.x-xxx.tar.gz
This will create the subdirectory syndex-7.0.x (containing all the distributed files). The executable is the file named syndex-7.0.x in the bin directory.

  • Under Windows, add it a .exe extension. In addition for Windows 7, execute syndex-7.0.x.exe in Windows XP SP2 compatibility mode.

If you experience any installation problem and the answer is not in the FAQ, please e-mail us a description of the problem, with enough information to let us a chance to resolve it.

From executive files to source code

SynDEx generates executive files containing macro-code. To translate this macro-code into a source code, you can use the GNU version of the m4 macro processor (
www.gnu.org). See the reference manual for more explanation.
