SysML - Modeling the arithmetic functions block

Using block diagrams and parametric diagrams to model the arithmetic functions block

As seen in the previous figure, the pressure device block consists of several sub modules, amongst which we can find the ARTH (arithmetic functions) block. We will now describe the block diagram of this module using a SysML block diagram. Here, using SysML constraint blocks, we will first define the relationships between the ARTH module and various other arithmetic equations that are used in this functional block, as shown in the figure on the right.



In order to precisely determine how the ARTH module performs its operations, the SysML parametric diagram is used, as shown in the figure on the left.
