Components may be organized into a hierarchy tree. The component which has other components below it is called a parent, and the elements below–children. Hierarchy allows to divide a program logically, making some components dependent on the others.
In the iSMA Tool hierarchy is presented in the Workspace Tree window and on the Property Sheet view as a tree, whose superior element is a parent and inferior elements are children.
The components’ hierarchy on the Wire Sheet view is limited to one generation. After opening of a parent component, the Wire Sheet view shows a schematic with all the children components distributed in the view. The figure below shows an opened parent component Boiler with its children in the Property Sheet view on the left and in the Wire Sheet view on the right.
