Error(14566): The Fitter cannot place 4 periphery component(s) due to conflicts with existing constraints (4 BYTE(s))

Description

You may see the fitter error messages when you compile Agilex™ 7 M-Series EMIF IP and Agilex™ 5 EMIF IP with full EMIF IP pin location assignments with Quartus® Prime Pro Edition Software versions 24.1 beyond.

Resolution

To workaround this Intel® recommends to manually constraints some interface signals and allow Quartus® fitter to place the pins. For this method of I/O placement, you must constraints the following signals

• PLL reference clock
• RZQ pin
• MEM_RESET_N
