Does the Quartus II software version 9.0 support hybrid external memory interfaces with a data group that wraps around a corner on a Stratix IV device?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Yes, it is possible to create data groups that wrap over column (vertical) and row (horizontal) I/Os from adjacent sides on a Stratix® IV device in the Quartus® II software version 9.0. Enable this functionality by using a Quartus II ini variable.

If one does not exist, create a text file called quartus.ini in your project directory and add the following text:

tgx_allow_mem_interface_wrap_around_corner = on

The Quartus II software must be re-started before the ini variable is effective.

Future versions of the Quartus II software will support hybrid interfaces for Stratix IV devices without the need for the ini variable.
