Unfortunately the Embedded Board Planner tool has been discontinued. We'll be looking to bring more design tools to the Resource & Design Center in the future. However, we do offer other services like complimentary schematic and layout review services, design-in test tools (with certain ones available on a free loan basis), evaluation kits available for purchase by product developers, software developers and system integrators, or request current silicon samples—free of charge—through Intel’s embedded samples program.
Learn more in the 'Sample & Buy' or the 'Design Resources' tabs found at Resources for Embedded and IoT Designers.
Hope this helps,
