IP: Memory Interfaces and Controllers

Error(20714): OCT "emif_fm_0_oct_oct_rzqin~pad" requests I/O standard "1.2-V POD" and Rt resistance "Parallel 50 Ohm with Calibration", but this I/O standard only supports Rt resistance ""Parallel 60 Ohm with Calibration".

Description

In the Intel® Quartus® Prime Pro Edition software version 20.1, you may see the following error during compilation if the Data Bus Input mode is set to 50 ohm with calibration under the FPGA I/O tab of the Intel Agilex® QDR-IV IP.

Error(20714): OCT "emif_fm_0_oct_oct_rzqin~pad" requests I/O standard "1.2-V POD" and Rt resistance "Parallel 50 Ohm with Calibration", but this I/O standard only supports Rt resistance ""Parallel 60 Ohm with Calibration". 

Workaround/Fix

To work around this problem, set the Data Bus Input mode to 60 ohm with calibration under the FPGA I/O tab of the Intel® Agilex® QDR-IV IP.

The 50 ohm with calibration setting for the Data Bus Input mode is planned to be supported in the future.
