Modeling the arithmetic functions block¶
As seen in the previous figure, the pressure device block consists of several sub modules, among which we also find the ARTH (arithmetic functions) block. We will now describe the block diagram of this module using the 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 Figure 26.

In order to precisely determine how the ARTH module performs its operations, the SysML parametric diagram is used, as shown in Figure 27.
