In [1], several methods for decomposing an ordinary, safe Petri net
into a flat, unit-safe NUPN [2], have been proposed. These methods
are implemented in a complete tool chain involving SAT solvers, SMT
solvers, and tools for graph coloring and finding maximal cliques.
From a data set of 12,000+ NUPN models, 51,000+ SMT formulas have
been generated, out of which a subset of 1200 interesting formulas
to be used as SMT-LIB 2.6 benchmarks was carefully selected.
