AR# 50699 MIG 7 Series - VCC_AUX can get set incorrectly in certain multi-controller configurations

Description

Version Found: v1.5
Version Resolved and other Known Issues: See (Xilinx Answer 45195).

The MIG 7 Series GUI can incorrectly set the default VCC_AUX for different controllers within the same VCC_AUX region.

For example:

1 DDR3 and 1 QDRII+ controller

Controller 0is placed in Bank 35 and usesaVCC_AUX=2.0V by default.
Controller 1 is placed at Bank 33 and uses a VCC_AUX=1.8V by default.

Solution

When this situation occurs, the MIG GUI will prevent the user from proceeding to the next step in the IP generation flow. Xilinx recommends upgrading to the latest version of MIG to work around the problem; it is possible to generate each controller individually and then combine them into your own top-level wrapper.
