LTL3BA is a translator of LTL formulae to Büchi automata. It is based on the popular tool named LTL2BA written by Denis Oddoux and Paul Gastin (available at http://www.lsv.ens-cachan.fr/~gastin/ltl2ba/).
LTL3BA further improves LTL2BA's performance. Most modifications are described in the paper:
T. Babiak, M. Křetínský, V. Řehák, and J. Strejček: LTL to Büchi Automata Translation: Fast and More Deterministic, in Proceedings of TACAS 2012, volume 7214 of LNCS, pages 95-109. Springer-Verlag, 2012.
LTL3BA supports output in Hanoi Omega-Automata (HOA) format since version 1.1.0. More information about HOA can be found here: http://adl.github.io/hoaf/
In order to compile LTL3BA, the BuDDy library (http://sourceforge.net/projects/buddy/) is needed.
Great app ltl3ba
small and efficient and gets the job done.
