+Generated by the tool Averroes 2 (successor of [1]) which implements safety property
+verification on hardware systems.
+
+This SMT problem belongs to a set of SMT problems generated by applying Averroes 2
+to benchmarks derived from [2-5].
+
+A total of 412 systems (345 from [2], 19 from [3], 26 from [4], 22 from [5]) were
+syntactically converted from their original formats (using [6, 7]), and given to 
+Averroes 2 to perform property checking with abstraction (wide bit-vectors -> terms, 
+wide operators -> UF) using SMT solvers [8, 9].
