Center node: "a high level ltl synthesis format tlsf v1 0"
  Abstract: We present the Temporal Logic Synthesis Format (TLSF), a high-level format to describe synthesis problems via Linear Temporal Logic (LTL). The format builds upon standard LTL, but additionally allows to use high level constructs, such as sets and functions, to provide a compact and human readable representation. Furthermore, the format allows to identify parameters of a specification such that a single description can be used to define a family of problems. We also present a tool to automatically translate the format into plain LTL, which then can be used for synthesis by a solver. The tool also allows to adjust parameters of the specification and to apply standard transformations on the resulting formula.
