I tried using the bc2cnf tool to generate the DIMACS CNF file of a boolean equation.
The input file contains the equation of an AND gate as shown below :
BC1.1
f := A & B;
ASSIGN f;
Command used: ./bc2cnf -v inp.txt opt.txt
Content in the output file:
c The instance was satisfiable
c A <-> T
c B <-> T
c f <-> T
p cnf 1 1
1 0
Here, it can be observed that the correct DIMACS CNF format of the AND gate is not generated.
Please let me know how this problem can be rectified.
Use commandline parameter -nosimplify
to suppress bc2cnf
optimization.
Result is
c f <-> 1
c B <-> 2
c A <-> 3
p cnf 3 4
-1 2 0
-1 3 0
1 -3 -2 0
1 0
bc2cnf
has a number of useful parameters. Try bc2cnf -?
to get help.
