Benchmark

non-incremental/QF_ABV/brummayerbiere/fifo32in06k05.smt2 

This benchmark comes from bounded model checking of two fifo implementations.
The fifos are resetted once at the beginning.
We try to verify behavioral equivalence with k-induction.
All different constraints are disabled.
Fifo inputs: 'enqueue', 'dequeue', 'reset' (active low) and 'data_in'.
Fifo output: 'empty', 'full' and 'data_out'.
Bit-width: 32
k: 5
The fifos have an internal memory of size 64, respectively modelled as array.
