You can easily navigate to the definition of any named construct, such as a port, signal, entity, etc. Place the cursor on the identifier, right-click, and select Go to Definition. The editor immediately jumps to the definition.

You can also navigate your code like a web browser by clicking hyperlinks. When you hold down the Ctrl key, hyperlinks will appear in your editor. Clicking a link (while holding that Ctrl key) navigates you to the target of the link.

When Go to Definition on an identifier points to itself, VS Code performs a Find references search in a peek window. This behavior can be customized via the editor.gotoLocation.alternativeDefinitionCommand setting.

Go to declaration

In most cases, definition and declaration in Sigasi refer to the same concepts. Go to definition is the behavior triggered by VS Code when you Ctrl+Click on an identifier. There’s one notable exception to consider: extern methods in Verilog.

class Animal;
    extern function string cry(); // declaration
endclass

function string Animal::cry(); // definition
    return "bzzz";
endfunction

The example above first declares the method cry and its signature (no arguments; returns string). Thereafter, the extern method’s body is defined. You can use Go to Definition ( Ctrl+Click ) to jump from the declaration to the definition. To jump from the definition to the declaration, right-click the cry in the definition and select Go to Declaration. In VHDL, similar navigations can be performed via Go to implementations, e.g., to jump from a component declaration to its corresponding entity.

When Go to Declaration on an identifier points to itself, VS Code performs a Find references search in a peek window. This behavior can be customized via the editor.gotoLocation.alternativeDeclarationCommand setting.
