We describe a procedure for the generation of functional digraphs up to isomorphism; these are digraphs with uniform outdegree 1, also called mapping patterns, finite endofunctions, or finite discrete-time dynamical systems. This procedure is based on an algorithm for the generation of connected functional digraphs, which is then generalised to arbitrary ones. Both algorithms have an $O(n^3)$ delay between consecutive outputs.
