There are a number of ways to place text in a circuit.
-
Each unexpanded instance of a cell has text that describes it, and its ports.
- Each export has a text label.
- Nodes and arcs can be named (with Object Properties...) so that they have text on them.
They can also have additional attributes that appear as text (for example, NCC annotations,
Spice multipliers, Verilog transistor strength, etc.)
- Certain primitive nodes (such as the Flip-Flop component of the Schematic technology)
have text as an integral part of their image.
- It is even possible to create a special node that is only text
(with some of the commands under the "Misc" entry of the component menu:
"Annotation Text", "Spice Code", "Spice Declaration", "Verilog Code", and "Verilog Declaration").
- Schematic and icon cells can have parameter definitions,
and the instances of those cells can have parameter values
(see Section 6-8-5).
Essentially, every piece of text on the display is tied to some node or arc (or occasionally a cell).
By understanding the relationship between text and its attached object,
it becomes easy to manipulate that text.
The visibility of text can be controlled with the "Layers" tab of the sidebar
(see Section 4-5-3).
This allows you to reduce the clutter of text on the display.
