Why does the slew rate value become unset after upgrading External Memory Interfaces (EMIF) IP in Agilex™ 7 FPGA F-Series and I-Series devices?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 24.3.1 and earlier, the slew rate values in the FPGA I/O tab of External Memory Interfaces (EMIF) IP might change to unset after upgrading the IP to a newer version.

Resolution

To work around this problem, follow these steps:

1. Toggle the Use default I/O settings checkbox.
2. Change slew rate to desired settings.

This problem is fixed beginning with the Quartus® Prime Pro Edition Software version 25.1.
