Modifying Existing Macros
Note: Double clicking on the top schematic name or the name of any
of its underlying schematic macros loads that schematic to the screen
for viewing and editing.
If you want to make some changes to an existing macro schematic,
perform the following steps:
1.
2.
3.
4.
When you change and save a hierarchical macro, you change all
instances of this macro in the entire design. If the modified macro
schematic has different I/O pins, its symbol changes and the pins
may not match their previous locations on the schematics. If this
happens, the wrong wires are automatically disconnected and will be
marked with crossed circles. These wires must be manually
reconnected by dragging the crossed circles over the target pins and
then releasing the mouse button.
If you edit a macro from the system library that comes with the
product, you cannot save it in the system library. You can only save it
into a project library. For clarity, use a different name for the modified
macro so that you can always be sure which symbols are currently
used on the schematics.
Push into the schematic macro by clicking the Hierarchy Push/
Pop icon and double clicking on the macro symbol.
Select the Select and Drag toolbar button to enter edit mode.
Make changes to the schematic.
