SSRAM on DE4 development board

We're trying to access the SSRAM on the DE4 development board, which I believe is the IS61NVP102418 SSRAM.

It seems as though the correct way to do this in Qsys is with a generic tri-state controller, and a tri-state bridge. However, there is no preset for the chip on the DE4 board, and the specifications seem to differ enough to make editing the configuration manually necessary.

Has anyone had any success accessing the SSRAM on the DE4 board, and what configuration in the Controller gives the correct signals to interface with the SSRAM controls exposed by the system builder?

Thanks
