Chapter III: HIERARCHY

icon

Moving Up and Down the Hierarchy

icon


Each editing window in Electric displays a single facet. Editing changes can only be made to that facet, and not to any subfacets that may have instances. Thus, you may be able to see the contents of a facet instance, but you cannot edit it. However, if a facet instance is highlighted, the Down Hierarchy command of the Facets menu will switch editing to that highlighted facet. The window scaling is preserved so that the facet definition is shown where the instance appeared.

The Up Hierarchy command pops you to the next higher facet in the hierarchy. If there was an associated Down Hierarchy command, then this places you at the previous window display, with the current scale and position. If the Down Hierarchy command was not used, Electric attempts to figure out the next higher facet in the hierarchy. The command fails if no descent path is saved and none can be clearly determined from the hierarchy. If an exported port is selected when the Up Hierarchy command is issued, that path is followed up the hierarchy. If there are multiple possibilities (because the current facet is used in many locations) then you will be prompted for a specific location.
