2.3.1. Top-Down Design Methodology Overview

In a top-down design methodology, you plan the design at the top level, and then split the design into lower-level design blocks. Different developers or IP providers can create and verify HDL code for the lower-level design blocks separately, but one team lead manages the implementation project for the entire design.

In the top-down methodology, you can use core block reuse to preserve the core logic by exporting the .qdb file. Another developer working on the same project can then reuse the core logic .qdb file.

You can similarly preserve the root partition by exporting the root .qdb file, using the root partition reuse flow, and then reusing that root partition in the same project.
