32.16.4 Design Hierarchy View
Design Hierarchy View presents recursively the instances in a Verilog module or the instances in a VHDL entity or component implementation. Cross-language design hierarchies are also supported.
Position the editor cursor on the name of a design element and press
Shift+F4 or right-click and choose
Show > Design Hierarchy from the context menu.
The Design Hierarchy View opens with the chosen element set as the top of the hierarchy. You can also go to menu
Window > Show View > Design Hierarchy to open the view.
Cancel Current Operation Stops the view operation in progress, for example a search.
Select Top A drop-down menu/pop-up dialog to select from
top modules for Verilog or
top architectures for VHDL. For Verilog, a
top element is a module that instantiates other design elements and it is not itself instantiated. Similar for VHDL
History List Click to see the previously inspected elements.
Show/Hide Ports Shows or hides the ports of the selected element. You can set the ports panel to the right or below the hierarchy.
Show PD Shows or hides power domain information. You can choose to see the power domain names in the node labels, and distinctive foreground or background colors for all nodes belonging to the same power domain.
Prepend Library Prepend to the node label the name of the library to which the instance belongs.
You can scroll through the tree of instances using:
the mouse scroll wheel
the Up arrow, Down arrow, PgUp, PgDn keys
the vertical button bar on the right side of the tree
go to top of tree
up one page
up one element
down one element
down one page
go to bottom of tree
Note: The up/down buttons are grayed out when reaching the top/bottom of the tree.
double-click on an instance to go to its declaration.
Double-click on a port to go to where it is connected.
Right-click on an instance in the hierarchy and you have the following options :
Show Usages (References) Search for the references of the selected instance. More details
Show Design Hierarchy Show the design hierarchy starting from the selection.
Show Diagram Show the design diagram for the current selection. More details
Copy Copy the label text of the selected instance to clipboard.
Copy Hierarchy Path Copy the hierarchy path of the selected instance to clipboard. You can change the segment separator from
Window > Preferences > DVT.
Right-click on a port and you have the following options :
Trace Drive / Load / Drive and Load / In Subinstance See
Show Usages (References) Search for the references of the selected port. More details
Readers / Writers See
Show Diagram Show the Finite-State Machine for the current selection. More details
Show Connections Diagram Show the Schematic Diagram of the selected port and all the instances connected to it
Copy Copy the label text of the selected port to clipboard.
Copy Hierarchy Path Copy the hierarchy path of the selected port to clipboard. You can change the segment separator from
Window > Preferences > DVT.
You can use the filters to locate a specific instance or port. You may use slash '/' characters to filter hierarchically one level and '//' to filter hierarchically all the levels. You may use the dot '.' character to filter instances that contain a specific port. The ports that match the filter are promoted to the top of the ports panel. See
Quick Search for more details.
|Filter by instance name. All instances that contain the filter text are shown.||
|Filter strict hierarchy. All instances that contain the filter text and are in a direct hierarchical relationship (father/son) are shown.||
|Filter non-strict hierarchy. All instances that contain the filter text and are in a direct or indirect hierarchical relationship (ancestor/../../descendant) are shown.||
|Filter strict hierarchy and show all descendants. Same results as for filter strict hierarchy, but including all descendants of the matched instances.||
|Filter strict hierarchy and show direct descendants. Same results as for filter strict hierarchy, but including the sons of the matched instances.||
|Filter by port name. All instances with ports that contain the filter text are shown.||
|Filter by hierarchy and port name. Hierarchical filtering and port filtering may be combined.||
