1. Arria 10 External Memory Interface Example Design Guidelines
Quartus Prime Software v17.0

2. Introduction
Intel’s EMIF IP has an optional synthesizable example design that can be generated to demonstrate a complete memory interface solution
This design can be used by customers for initial interface validation
This slide deck covers the following topics:
EMIF IP generation
Synthesizable example design generation
For more information regarding the EMIF IP and parameterization, refer to the Implementing and Parameterizing IP section in the External Memory Interface Handbook
*EMIF = External Memory Interface

3. Software Requirements
Quartus Prime Software v17.0

4. Creating a Quartus Prime Project
The following slides demonstrate how to create a Quartus Prime project
Starting with Quartus Prime v17.0, users must create a Quartus Prime project before generating the EMIF IP and accompanying example design project
Launch Quartus Prime and select New Project Wizard
Or File > New Project Wizard
Press Next, select a directory and name for the project, and select Next
New Project Wizard

5. Creating a Quartus Prime Project
Select Empty project and continue to press Next until you reach the Family, Device, and Board Settings option
Select Arria 10 (GX/SX/GT) under Family and then select your specific Arria 10 device under Available devices
You can filter the available devices list using the options on the right, including the Name filter
Press Finish

6. Generating the EMIF IP
The following slides demonstrate how to generate the EMIF IP and accompanying example design project
Double-click Arria 10 External Memory Interfaces from the IP Catalog
Or Tools > IP Catalog
If the IP Catalog is not visible: View > Utility Windows > IP Catalog

7. Generating the EMIF IP
Double-clicking on Arria 10 External Memory Interfaces opens the IP Parameter Editor
Provide a File Name for the EMIF IP
Click Create

8. Configuring the EMIF IP
Under Memory Protocol, select the appropriate Protocol from the drop-down list
Under the General tab, select the desired Speed Grade and Memory clock frequency
Configure the EMIF IP by selecting appropriate settings under each tab
For more information refer to the Implementing and Parameterizing IP section in the External Memory Interface Handbook

9. Memory Device and Development Kit Presets
Note that there are predefined configurations available for various memory devices
In the Presets window, select the desired memory device present and click Apply
This will populate all the fields with vendor specific settings
A custom memory device preset can also be created by clicking New and entering the configuration data
There also exists presets for existing development kits in the Presets window, where you can select the appropriate one and click Apply

10. Generating the EMIF Example Design Project
After configuring the EMIF IP, select the Example Designs tab and make sure the Synthesis checkbox is selected under Example Design Files
Select Generate Example Design
Or Generate > Generate Example Design

11. Generating the EMIF Example Design Project
After selecting Generate Example Design, a pop-up window will appear asking you to provide a Path to store the example design
Point to the desired location and select OK
In this example, a new emif_0_example_design folder will be created in the existing emif_example directory (created in step 2, slide 4)
This folder will contain all of the EMIF example design files

12. Generating the EMIF Example Design Project
Upon successful example design generation, a dialog box will open with design completion detail; press Close
Pin assignments are automatically generated when a development kit preset is selected
If no development kit preset was selected, pin assignments need to be manually assigned

13. Saving the Configured EMIF IP
After closing the window upon successful example design generation, click Finish in the IP Parameter Editor window
A window will pop-up prompting you that recent changes have not been generated
Select Yes if you want to save the IP for future reference/use, otherwise select No
If you selected Yes, select Generate on the next window and then Finish once the generation has completed

14. EMIF Example Design Files
After IP generation is complete, an example design directory will be created in the location selected during step 15, slide 11
Generated example design QSYS file
Open this file to add/remove/modify IPs in the example design
Generated external memory interface IP file
Open this file to modify the EMIF IP
Quartus Prime project file
Open and compile this project with Quartus Prime software v17.0
