Benchmark

non-incremental/QF_BV/bruttomesso/simple_processor/simple_processors_004_003_0004.smt2 

The benchmark encodes 3 simple processors
   receiving instructions to decode and execute.
   The processors compute the same function on 4 operands but
   their decoding units differ in the way they
   communicate the result.
   We check that, modulo reinterpretation of the
   decoded instructions, the result is the same.
   We added a "mode" flag to force the decoding
   unit to return the result in two different ways.

   The encoded design is a modification of Example 11.2, at page 20 of
   "Introduction to Verilog", by Peter M. Nyasulu
   available online.
