Here are several platforms that I suggest for you to gain knowledge about the memory controller. Hope this is helpful for you.
1. EMIF Handbook:
2. EMIF Support Center Website:
3. EMIF User Guide ( Arria 10):
Regarding the probing system, can you help to clarify more on which probing are you referring? Are you referring to on board probing or FPGA internal probing?
If it is FPGA internal probing, you can use SignalTap Analyzer to probe on Avalon MM bus transaction. If no then please help to elaborate more so that I can understand your inquiry better.
