how to config priority of EMIF on agilex 7 FPGA

Hello lidongyang,

Please find my feedback in the point below.

"I wonder how to change the priority of EMiF in Qsys configuration? for agilex 7 FPGA"

• You need to set the arbitration in the QSYS for related conduit/connection.
• Higher number represent higher priority.
• You may refer to this link for more details: 5.1.5.1. Round-Robin Arbitration (intel.com)

"How can I set Enable Command Priority Control, and how to connect ctrl_user_priority_hi?"

• Enable the option in EMIF IP -> Controller tab -> Efficiency -> Enable Command Priority Control.
• Connect the ctrl_user_priority_hi to your user logic.
• When this signal is high during read/write request, it will set the read/write request to high priority.
