Bounded model checking (BMC) is a verification method that searches for runs violating a property using a SAT or SMT solver. Previous SMT-based BMC approaches for TAs search for finite counter-examples and infinite lasso-shaped counter-examples. This paper shows that lasso-based BMC cannot detect counter-examples for some linear time specifications expressed, e.g., with LTL or Büchi automata. This paper introduces a new SMT-based BMC approach that can find a counter-example to any non-holding Büchi automaton or LTL specification and also, in theory, prove that a specification holds. Different BMC encodings tailored for the supported features of different SMT solvers are compared experimentally to lasso-based BMC and discretization-based SAT BMC. %G English %Z TC 6 %Z WG 6.1 %2 https://inria.hal.science/hal-01528739/document %2 https://inria.hal.science/hal-01528739/file/978-3-642-30793-5_6_Chapter.pdf %L hal-01528739 %U https://inria.hal.science/hal-01528739 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC6 %~ IFIP-WG6-1 %~ IFIP-FORTE %~ IFIP-FMOODS %~ IFIP-LNCS-7273
