Construction of New Blocks
For most applications, blocks provided already by Activate are enough to construct models. Complex expressions can be encapsulated in Expression blocks presented in Chapter 7 and if it is desired to expose an advanced functionality through a single block, there is always the possibility of using a masked Super Block where the functionality is realized by a diagram. So there is little need to construct truly new Activate blocks. Constructing such new blocks is usually done mainly by library developers. Developing a programmable Super Block or a new basic block is not always an easy task but a block builder (BlockBuilder) tool is provided in Activate that facilitates such developments. The BlockBuilder GUI contains multiple tabs that can be used to define various properties of the new block. This graphical interactive tool will be briefly presented in Section 13.5.
