You may experience the above error when setting the Arria 10 DDR3L IP I/O tab Slew Rate option to Slow on the Address/Command signals. Slow slew rate is only supported when the output termination is turned off, and SSTL-135 does not allow the output termination to be turned off.
Device Family: Intel® Arria® 10 GT, Intel® Arria® 10 GX, Intel® Arria® 10 SX
Area: Component, EMIF
Perform board-level simulations with Fast slew rate to determine the optimal external termination values.
This issue will be fixed in a future release of the Quartus® II software.
