ABSTRACT
Block diagrams can currently be drawn where the block direction, speciŸed by the enumerated type, “EBlockDirection”, is set to “e_right” by default, implying that the block points to the right. However, if the user wants to reverse the direction of a block, e.g., a Gain block to be used in a feedback rather than a feed-forward path, where the block points in the direction of the signal ¦ow, then a “reverse block” option should be available to provide this change. The general steps concerning the implementation of this functionality are as listed where speciŸc details are provided in the sections that follow.
