Graphic Editor: Creating a Hierarchical Design

This example describes how to create a hierarchical design using the Graphic Editor. This design is functionally equivalent to AHDL: Creating a Hierarchical Design. The top-level file, top.gdf, calls the two lower-level files bottom1.gdf and bottom2.gdf. See the figures below.

bottom1.gdf
bottom1.gdf
bottom2.gdf
bottom2.gdf
top.gdf
top.gdf

You must create the symbol files bottom1.sym and bottom2.sym so that the lower-level files can be instantiated into the top level. To create the symbol files:

  1. Open one of the lower level files (bottom1.gdf or bottom2.gdf)
  2. Specify the project name by choosing the Set Project to Current File command (File menu).
  3. Choose Create Default Symbol (File menu). MAX+PLUS II creates the .sym file.
