Why do I see that Intel® EMIF AXI-Lite Bus (NoC or Fabric) is unresponsive during simulation or hardware testing?

Environment

    Intel® Quartus® Prime Pro Edition
    External Memory Interfaces (EMIF) IP
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

When using Intel® EMIF AXI-Lite Interface (NoC or Fabric), the AXI-Lite Bus is not working properly and is unresponsive after reset.

 

 

 

Resolution

To communicate properly with the AXI-Lite interface, you must wait for at least eight clock cycles (NoC initiator or Fabric clock) after the reset of the interface is de-asserted before issuing any commands.
