AutoFunc

Code action. Fills in the missing arguments of a function or task call from its signature. Put the cursor on the function or task name of a call that has fewer arguments than the signature. A complete call gets no action.

task add_number(input int a, input int b, output int result);
    result = a + b;
endtask

module top;
    int x, y, sum;

    initial begin
        add_number(x, y);
    end
endmodule

With the cursor on add_number, the call becomes:

        add_number(.a(x), .b(y), .result(result));

Arguments you already wrote are kept, and each missing one is filled with the parameter's own name. An empty call such as add_number( becomes add_number(.a(a), .b(b), .result(result));. With use_named_arguments = false the same call becomes add_number(x, y, result);.

The result is laid out by the formatter, so a long call wraps as your function-call settings say.

Section	Option	Default	Description
autofunc	indent_size	4	Indent for multiline argument lists. Does not follow [format].indent_size (default 2), so set both if you want them to match
autofunc	use_named_arguments	true	Generate .arg(value) instead of positional arguments
