3.15.4. Arria® 10 EMIF Debugging Examples

This topic provides examples of debugging a single external memory interface, and of adding additional EMIF instances to an I/O column.

Debugging a Single External Memory Interface

  1. Under EMIF Debug Toolkit/On-Chip Debug Port, select Add EMIF Debug Interface.

    (If you want to use the On-Chip Debug Port instead of the EMIF Debug Toolkit, select Export instead.)

  2. If you want to connect additional EMIF or PHYLite components in this I/O column, select Enable Daisy Chaining for EMIF Debug Toolkit/On-Chip Debug Port.

Adding Additional EMIF Instances to an I/O Column

  1. Under EMIF Debug Toolkit/On-Chip Debug Port, select Export.
    Figure 106. EMIF With cal_debug Avalon Slave Exported


  2. Specify a unique interface ID for this EMIF instance.
  3. If you want to connect additional EMIF or PHYLite components in this I/O column, select Enable Daisy Chaining for EMIF Debug Toolkit/On-Chip Debug Port.
