Structure View

Use the structure view to see the outline of a long file at a glance and to jump to any class, method or port without scrolling or searching. The Structure tool window (⌘7 on macOS, Alt+7 on Windows/Linux) and the File Structure popup (⌘F12 / Ctrl+F12, or Navigate | File Structure) show the declarations of the current file as a tree.

Try it

The steps use the sample project; open it and wait for indexing first. Nothing is edited, so there is nothing to undo.

1. Open uvm/my_pkg.sv and press ⌘F12 (Ctrl+F12; hold Fn if F12 does nothing on a laptop).
2. The popup shows my_pkg with its classes. Under my_driver you see vif, new, build_phase and run_phase; under my_item, addr, data, the constraint c_addr and new.
3. Type run and press Enter. The popup closes and the caret (the text cursor) in the editor is on run_phase. (Escape closes the popup without jumping.)
4. Press ⌘7 (Alt+7) to open the same tree in the Structure tool window; it stays open as a side panel (usually on the right; press ⌘7 / Alt+7 again to hide it), and a click on an entry (for example connect_phase under my_env: the caret moves to that method) jumps to it.

If the tree is empty or the shortcut does nothing, see If it doesn’t work.

What it shows

Under	Shown
The file	modules, interfaces, programs, packages, classes, interface classes, checkers, user-defined primitives, functions and tasks
A module, interface or program	parameters, ports, nets, variables, typedefs, instances (also gate instances such as and g1 (…)), functions, tasks, modports, clocking blocks, properties, sequences, covergroups, checkers, classes, generate blocks (by their label)
A package	parameters, typedefs, variables, functions, tasks, classes, checkers
A class	properties, constraints, covergroups, the constructor new and methods (also as extern prototypes), typedefs, parameters, nested classes
A generate block	its declarations (a block without a label adds them to the enclosing module)

Each entry shows its kind (port, net, task, …). Local variables of functions, tasks and procedural blocks are not listed, and neither are the ports and items of a checker or primitive (the checker or primitive itself is listed). Click an entry, or pick it in the popup, to jump to its name. The tree follows your edits.

Two options of the Structure tool window (its toolbar buttons) help in a long file: the tree can be sorted alphabetically, and with Autoscroll from Source the entry around the caret (the text cursor) is selected: the method whose body you are in, the module, the declaration under the caret.

Limitations

• Only declarations in the active branch of an `ifdef are listed (see Conditional compilation).
• The body of an out-of-block method (function void C::f(); … endfunction, written outside its class) has no entry of its own; its prototype in the class is listed. With the caret in such a body, Autoscroll from Source selects the enclosing package (or nothing at file level), not the prototype.

If it doesn’t work

You see	Likely cause	What to do
The tree is empty	The file is not a SystemVerilog file (.sv, .svh, .v), or the plugin is disabled	See Installation
A declaration is missing	It is in code an `ifdef switches off, or it is a kind that is not listed (a local variable)	See the limitations above
The shortcut does nothing	Your keymap differs, or on a laptop you must hold Fn for F12	Use Navigate | File Structure, or View | Tool Windows | Structure
