IP Product: DDR3 SDRAM Controller MegaCore supporting UniPHY

Does UniPHY External Memory Interface debug toolkit support all the speed grades for Stratix III and Stratix IV FPGA devices?

Description

Currently, not all Stratix® III and Stratix IV device speed grades are supported by the UniPHY external memory interface debug toolkit.

In the debug toolkit Project Settings panel, the device speed grade is selected and then the Update Project Settings button is clicked.

The workaround is as follows for these device speed grades:

For Stratix IV -I1, -I2    use C2

For Stratix III -I2           use C2

This issue is planned to be fixed in a future version of Quartus II.
