I am maintaining and developing an open-source toolkit with SDF analysis, transformation and mapping algorithms. SDF3 offers many standard SDFG transformation and analysis algorithms, advanced MP-SoC binding and scheduling functions for SDFGs, an SDFG random graph generator,links to visualization and simulation software. SDF3 is available as a set of command-line tools and via a C/C++ API. You can find more information on the tool here.
