VHDL Toolbox Pages

Access

To model a VHDL design, drag icons from the VHDL toolbox pages and drop them on your diagram.

Ribbon

Design > Diagram > Toolbox : Search > Specify 'VHDL Constructs' in the 'Find Toolbox Item' dialog

Keyboard Shortcuts

Alt+5 : Search > Specify 'VHDL Constructs' in the 'Find Toolbox Item' dialog

Other

You can display or hide the Diagram Toolbox by clicking on the Chevron Right or Chevron Left icons at the left-hand end of the Caption Bar at the top of the Diagram View.
