Tree window hierarchical view

ModelSim provides a hierarchical, or "tree view" of some aspects of your design in the Main window Structure tabs and the Structure, Signals, Variables, and Wave windows.

HDL items you can view

Depending on which window you are viewing, one entry is created for each of the following VHDL and Verilog HDL items within the design:

VHDL items

(indicated by a dark blue square icon)
signals, variables, component instantiations, generate statements, block statements, and packages

Verilog items

(indicated by a lighter blue circle icon)
parameters, registers, nets, module instantiations, named forks, named begins, tasks, and functions

Virtual items

(indicated by an orange diamond icon)
virtual signals, buses, and functions, see "Virtual Objects (User-defined buses, and more)" for more information
