metaSMT - An Embedded Domain Specific Language for SMT

Logo metaSMT
metaSMT provides an easy to use Embedded Domain Specific Language (EDSL) for C++ similar to SMT-LIB. Various Satisfiability (SAT) and SAT Modulo Theories (SMT) solvers can be used directly over their API through the language. The main advantages of metaSMT are:
  • Engine independence through efficient abstraction layers
  • Simplified development of algorithms based on formal methods
  • Extensibility in terms of input language and reasoning engines
  • Customizability in terms of optimization and infrastructure
  • Translation of the input language into native engine calls at compile time
  • Theories and logics:
    • Simple Boolean expressions over Boolean predicates
    • Closed quantifier-free formulas over the theory of fixed-size bit-vectors (QF_BV)
    • Closed quantifier-free formulas over the theory of bit-vectors and bit-vector arrays (QF_ABV)
  • Assertion management:
    • Stack with push and pop (as in SMT-LIB 2.0)
    • Groups of assertions (creation, deletion)
    • Assumptions (valid during one SAT call)
  • Supported SMT solvers: Boolector, Z3, STP SWORD
  • Supported SAT solvers: MiniSAT (API), PicoSAT (API), Glucose (CNF files), PrecoSAT (CNF files), Plingeling (CNF files)
  • Other: CUDD, Aiger

Users of metaSMT
  • metaSMT is used in metaSMT-webifc, a portfolio solver with a web-based input interface. A variety of different decision procedures are provided which solve a given SMT instance, optionally in parallel.
  • metaSMT is used for constraint random verification of SystemC models. For more details see www.systemc-verification.org
  • metaSMT is used by the Software Reliability Group at Imperial College London for symbolic execution supporting multiple SMT solvers.
