Analysis problems of hybrid systems, involving nonlinear real functions and ordinary differential equations, can be reduced to SMT (satisfiability modulo theories) problems over the real numbers. The dReal solver can automatically check the satisfiability of such SMT formulas up to a given precision δ > 0. This paper explains how bounded model checking problems of hybrid systems are encoded in dReal. In particular, a novel SMT syntax of dReal enables to effectively represent networks of hybrid systems in a modular way. We illustrate SMT encoding in dReal with simple nonlinear hybrid systems.
