Creating a Schematic Macro (Bottom-Up
Methodology)
To create a schematic macro using a bottom-up methodology,
perform the following steps.
•
•
•
Before you start drawing a schematic, make sure that the neces-
sary libraries have been assigned to the project. You can view the
currently attached project libraries in the Files tab of the Project
Manager.
•
•
Enter your schematic design in the Schematic Editor, just like any
other flat design, with the following constraints:
•
•
To create the macro symbol, select Hierarchy
Symbol from Current Sheet from the Schematic Editor
window. The new symbol is automatically placed in the current
project’s working library.
To add additional libraries, select File
Libraries from the Project Manager.
When the Project Libraries window displays, select the
appropriate libraries and then click Add.
This operation transfers the selected libraries from the
Attached libraries window to the Project Libraries window,
which makes these libraries available to the Schematic Editor.
Each macro is a self-enclosed entity. Any connection to the
top-level sheet can only be performed through hierarchy
connectors.
The hierarchy connectors must be specified explicitly as
Input, Output, or Bidirectional. This specification is impor-
tant because the design entry tools automatically generate a
symbol. The location of the pins on the symbol depends upon
their schematic I/O definition (only inputs are on the left-
side of the symbol outline). If needed, edit this symbol in the
Symbol Editor.
