Description

This error may be generated by the Quartus® II software version 10.0 when creating an ALTLVDS_RX megafunction using the MegaWizard™ Plug-In Manager. This error occurs when Dynamic Phase Alignment (DPA) mode is enabled and the megafunction uses an external PLL for designs targeting Stratix® III, Stratix IV, Arria® GX, Arria II GX, HardCopy® III and HardCopy IV devices.

A patch is available to fix this problem for the Quartus II software version 10.0. Download and install Patch 0.32 from the appropriate link below.

This problem is fixed beginning with the Quartus II software version 10.0 SP1.
