tool chain inconsistency

[mmpour...@gmail.com]

Hi everyone,

I have a model (attached file, model.smt2) whose result must be UNSAT, and boolector itself returns the correct result:

boolector model.smt2

unsat

For sake of efficiency, I am using the following tool chain, but I receive a different result (SAT).

smt2 --Boolector--> aig

aig    --aigtocnf----> cnf

cnf    --cadical-----> result

boolector model.smt2 --beta-reduce-all -dam -dai|aigtocnf|cadical -q

s SATISFIABLE

v 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 -20 -21 -22 -23 24 -25 -26

v 68 69 -70 -71 -72 -73 74 75 -76 -77 -78 -79 80 81 -82 83 -84 85 86

Am I doing something wrong?

I am using:

boolector 2.4.1

aiger 1.9.9

picosat-965

lingeling-bbc-9230380-160707

cadical sc17

Thank you in advance.

Regards,

Mehdi
