Illegal Speed Grade Error with Arria V and Cyclone V Devices


This problem affects DDR2, DDR3, and LPDDR2 products.

The parameter editor allows you to select an unsupported speed grade for the target FPGA, resulting in an error message.


The workaround for this issue is to select only supported speed grade devices.

This issue will be fixed in a future version.
