For example, a geometrical dependency between two components that have to fit within a predefined space. + +The ESL compiler derives design dependencies from design and relations specifications. Figure 1 shows for example an MDM containing components, variables, design specifications, a relation, and a need. + +The component DSM (rows 1-2, cols 1-2) shows a design dependency between `pump` and `drive-mechanism`. This dependency is derived from design specification `dc-drive-length` that states that `drive-length` and `pump-length` must be equal. + +

+ +Design specification `dc-drive-length` yields a design dependency between the variables `drive-length` and `pump-length` as well. This dependency is shown within the variable DSM (rows 3-8, cols 3-8). + +Within the variable DSM one can see an additional dependency between `power-potential` and `power`. This dependency is derived from relation specification `efficiency-model` (row 11). - This content is not fully migrated, yet.
