How can I set the "Read data reordering depth" for AXI agent interface in the Platform Designer?

Environment

    Intel® Quartus® Prime Design Software
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

In the Intel® Quartus® Prime Software v22.4 and earlier version, the Platform Designer interconnect does not support out-of-order responses. Therefore, the setting of "Read data reordering depth" in each AXI agent interface should be set correctly to avoid any mismatch. 

Resolution

Follow these steps to find and set the Read data reordering depth in the AXI agent interface in the Platform Designer:

  1. Right-click on the target AXI agent interface in the Platform Designer.
  2. Choose Edit Component Instantiation.
  3. Choose the target AXI agent interface in Signals and interfaces tab, and you will see the Read data reordering depth in the Parameters tab.
  4. Edit the value of Read data reordering depth to match the agent interface behavior. If the agent interface processes all transactions in order, set Read data reordering depth to 1. If the agent interface may process all transactions out of order, set Read data reordering depth to greater than 1.
