1.3.1. Step 1: Compile the Flat Design

Follow these steps to compile the flat (non-partitioned) design:
  1. In the Intel® Quartus® Prime Pro Edition software, click File > Open Project and open the /tutorial_flat/top.qpf project file.
  2. To compile the flat design, click Compile Design on the Compilation Dashboard. The flat compilation can require 40 minutes or more, depending on your system.
