Create A2L from C/C++ source, Merge, Update addresses and Filter A2L files.

Automates A2L creation and management

Acam automates all steps of A2L creation and management in a software build, maximizing efficiency and quality by minimizing the need for human actions. A typical build chain is illustrated in the figure below. The black circles are tools in the suite.

[A2l creation and management]




There is no installation wizard. Just download the archive for your operating system and unzip it to a folder of your choice.

Acam1.6p0 Windows

Acam1.6p0 Linux

MacOs builds are not done fore each release but can be provided on request.


Acam uses Codemeter for license management. Hence Codemeter runtime is required. If it is’t already installed get it from

Acam for Windows needs Microsoft Visual Studio Redistributable. Download and install vc_redist.x64.exe if it isn’t already installed.

As much A2L information as possible is derived from debug information emitted by the compiler. Minimizing information which must be entered by the developer also minimizes development and maintenance effort hence enabling rapid development with high quality. Read more.

  • Option to suppress rename warnings in case of name clashes when merging A2L files.

However on cannot generate a generic A2L corresponding to the generic ANSI-C. The closest is to select to generate A2L for dSPACE V-ECU. However in this case TargetLink uses a dSPACE unique notation for variable identifiers in the generated A2L file).
  • Support for both ANSI and UTF-8 encoding.

  • Filtering of measurements and characteristics based on which functions they belong to.
Acam v1.0.4
  • Robustness improvements for parsing measurements and characteristics.
  • Filtering based on LAB files from for example ETAS INCA. This feature enables reuse of the main filter definition file across several projects or customers, hence improving consistency and maintainability.  It also enables filtering based on lists created in tools such as ETAS INCA and Vector CANape.

  • Corrected warning for redefinition of measurement/characteristic/axispts during merge.

Default is to issue redefinition warning and rename to avoid name clashes in merged a2l. With the new option –merge-functions UeA2lMerge will merge the function content instead.
