2.1.1. Generating a Custom Memory Presets File

This topic illustrates how to generate and configure memory device presets. You would do this if your design targets a memory component or DIMM for which the Quartus® Prime software doesn't already have presets.

These steps create an LPDDR4 presets file; however, the steps are similar for other memory protocols.

  1. In the IP Catalog window, select Memory Device Description IP (LPDDR4). (If the IP Catalog window is not visible, select View > IP Catalog.)

  2. In the IP parameter editor, provide an entity name for the memory device presets file (the name that you provide here becomes the name for the file) and specify a directory. Click Create.
