Datatypes and codatatypes are useful to represent finite and potentially infinite objects. We describe a decision procedure to reason about such types. The procedure has been integrated into CVC4, a modern SMT (satisfiability modulo theories) solver, which can be used both as a constraint solver and as an automatic theorem prover. An evaluation based on formalizations developed in the Isabelle proof assistant shows the potential of the procedure.
