< variation name > is the is the name you give to the controller you create with the
Megawizard.
The example driver is a self-checking test generator for the QDRII SRAM
controller. It uses a state machine to write data patterns to all memory
banks. It then reads back the data and checks that the data matches. If any
read data fails the comparison, the fail output transitions high for one
cycle and the fail permanent output transitions high and stays high.
The data patterns used are generated using an 8-bit counter per byte, with
each counter having a different initialization seed.
