Benchmark

non-incremental/QF_ABV/brummayerbiere/fifo32bc06k07.smt2

This benchmark comes from bounded model checking of two fifo implementations.
The fifos are resetted once at the beginning. We show that the
implementations are behaviorally equivalent up to a bound of 7 clock cycles.
Fifo inputs: 'enqueue', 'dequeue', 'reset' (active low) and 'data_in'.
Fifo output: 'empty', 'full' and 'data_out'.
Bit-width: 32
The fifos have an internal memory of size 64, respectively modelled as array.
