A block class is the same as a model class with the restriction that each connector component of a block must have prefixes input and/or output for all connector variables. The purpose is to model input/output blocks of block diagrams. Due to the restrictions on input and output prefixes, connections between blocks are only possible according to block diagram semantic.
