Synthesis of asynchronous circuits. Although asynchronous circuits often require more transitions on the computation path than synchronous circuits they generally have transitions only in areas involved in the current. If transitions on two inputs arrive at almost the same time the circuit can go into the wrong state depending on slight differences in the propagation delays of the gates which are known as race.
