Some optional components that can be useful for verifying aspects of the controller
and PHY operation are generated in conjunction with certain user-specified options.
These add-on components are self-contained, and are not part of the controller or
PHY, nor the example driver.
User Refresh Generator
The user refresh generator sends refresh requests to the memory controller when user
refresh is enabled. The memory controller returns an acknowledgement signal and
then issues the refresh command to the memory device.
The user refresh generator is created when you turn on Enable User Refresh under
Controller Settings on the General Settings tab of the parameter editor. The user
refresh generator is instantiated by example_top_v. and resides in the
example_project subdirectory.
Refresh Monitor
As its name implies, the refresh monitor monitors refresh commands from the
controller and verifies that those commands conform to the necessary refresh timing
parameters.
The refresh monitor is created when you turn on Enable User Refresh under
Controller Settings on the General Settings tab of the parameter editor. The refresh
monitor is instantiated by example_top_tb.v and resides in refresh_monitor.sv in the
rtl_sim subdirectory.
Data Corrupter
The data corrupter intercepts read data in the memory interface bus and introduces
errors to that data to test the error detection function in the memory controller. Both
the rate of error injection and the number of error bits are configurable (although the
per-byte parity protection feature supports only 1 bit error detection).
The data corrupter employs four types of error injection:

Throughout the four types of error injection tests, the data corrupter exercises a
walking-one pattern to confirm correctness.
