DDR3 HPS Interfaces Supported Only to 450 MHz on Arria V SoC ES Devices


This problem affects DDR3 products.

In Arria V SoC ES devices, the HPS hard memory controller supports DDR3 interfaces to a maximum of 450 MHz. Higher frequency interfaces are not supported.


The workaround for this issue is to not exceed 450 MHz with a DDR3 HPS interface on Arria V SoC ES devices.

This issue will be fixed in a future release.
