1.1. Step 1: Open the Design Example Project

This application note includes a design example and Tcl script files that demonstrate use of various ECO commands. You can download and restore the design example to follow along with the application note steps in the Intel® Quartus® Prime Pro Edition software.
  1. Save the design example project archive file to hard drive:
    an922_eco_demo_20_3.qar
  2. In the Intel® Quartus® Prime Pro Edition software version 20.3, click Project > Restore Archived Project, and then specify the an922_eco_demo_20_3.qar design example archive for the Archive name.
    This design example is verified with Intel® Quartus® Prime Pro Edition software version 20.3, but can be adapted for later versions with slightly different results.
  3. For Destination folder, specify a new directory to contain the restored design example project files. The project directory also contains the eco_demo_1.tcl through eco_demo_6.tcl Tcl scripts for this design example.
