module B = Kernel.Basic

module M = Api.Meta

This module declares all the types and signatures needed to implement an smt solver.

type logic = [

| `Qfuf
| `Lra

]

Qfuf is a logic with non-interpreted symbols, can be slow. Lra is linear arithmetic. Fast, but it requires an interpretation of CTS specification into linear arithmetic.

module type LOGIC = sig ... end

Any SMT Logic

type env = {

mk_theory : int -> Common.Oracle.theory;
(*
Compute a theory related to the target CTS specification.
*)
min : int;
(*
minimum number of universes to check
*)
max : int;
(*
maximum number of universes to check
*)
print : bool;
(*
print the problem in a file
*)

}

configures the SMT solver

type model = B.name -> Common.Universes.univ

model is a function that associate to each fresh universe a concrete universe.

module type SMTSOLVER = sig ... end

An SMT solver is a solver specific to one SMT such as Z3

module type SOLVER = sig ... end
