The following sub-sections describe the layout and working of each OpenECU block. Each sub-section follows the same form, including diagrams of the block and its mask, a description of its functionality and a description of the block's inports, outports and any parameters.
Some inports, outports and parameters have a valid numerical range or size of vector. If so, the range and size information is given beside the object's description using internal notation.
Table 5.1. Interval notation
| Notation | Range |
|---|---|
| (x, y) | x < value < y |
| [x, y) | x <= value < y |
| (x, y] | x < value <= y |
| [x, y] | x <= value <= y |
Some objects are not clipped to a range but folded into a range using modulo arithmetic and where this occurs, the description includes details.
