Heptagon/BZR is a synchronous dataflow language whose syntax and semantics is inspired from Lustre, with a syntax allowing the expression of control structures (e.g., switch or mode automata). Heptagon/BZR is a research compiler, whose aim is to facilitate experimentation. The current version of the compiler includes the following features:

• Inclusion of discrete controller synthesis within the compilation
• Expression and compilation of array values with modular memory optimization See https://gitlab.inria.fr/synchrone/heptagon for further informations.
