What component should I use instead of CFI flash interface controller core in Qsys?

Description

In the Quartus® II software version 12.1 and later, the CFI flash interface controller core is not shown in Qsys component library.  For CFI flash support, use the Generic Tristate Controller instead of the CFI component.  The Genertic Tristate Controller is availabe by selecting the Component Library and clicking on Qsys interconnect. In the generation window, choose Flash Memory Inferface(CFI) from Presets list on the right-hand side.
