SOPC Builder and Qsys Do Not Support Full-Rate DDR with HPC I in Simulation


SOPC Builder and Qsys do not support full-rate DDR designs using the high-performance controller (HPC I) in simulation. DDR2 designs are supported.

This issue affects all full-rate DDR designs with the high-performance controller (HPC), generated with SOPC Builder or with Qsys.

The design fails during calibration.


There is no workaround for this issue.

This issue will not be fixed.
