* spot/twaalgos/aiger.cc, spot/twaalgos/aiger.hh: Reimplement print_aiger for speed gain, also heuristics to minimize the number of gates as well as different encoding types have been added. * bin/ltlsynt.cc: Make the new options for print-aiger available. * tests/core/ltlsynt.test: Adjust tests.

/// \brief Encode and print an automaton as an AIGER circuit.

///
|
|
/// The circuit actually encodes the transition relation of the automaton, not
|
|
/// its acceptance condition. Therefore, this function will reject automata
|
|
/// whose acceptance condition is not trivial (i.e. true).
|
|
/// States are encoded by latches (or registers) in the circuit. Atomic
|
|
/// propositions are encoded as inputs and outputs of the circuit. To know
|
|
/// which AP should be encoded as outputs, print_aiger() relies on the named
|
|
/// property "synthesis-outputs", which is a bdd containing the conjunction of
|
|
/// such output propositions. All other AP are encoded as inputs. If the named
|
|
/// property is not set, all AP are encoded as inputs, and the circuit has no
|
|
/// output.
|
|
///
|
|
/// \pre In order to ensure correctness, edge conditions have
|
|
/// to have the form (input cond) & (output cond). The output cond
|
|
/// does not need to be a minterm.
