9   Compatibility

Starting with Simics 3.0, Simics has a backward compatible ABI for minor versions (third digit change). Any exceptions are noted in the release notes. As a result, user written modules can be moved to a newer minor Simics release without recompilation. The Simics API is backward compatible. If compiling towards a older major version API, the backward compatibility support must be explicitly requested in the module makefile, as described later in this chapter.
