My M9K blocks get always synthesized away!

Hey, I am using MegaFunction to instantiate M9K SRAM blocks in my design and the Quartus 17.0 software always syntheszies away my M9K blocks, my design consists of Reset signal and the memory blocks...

First, does the design run in simulation? You describe what the design is supposed to do, but does it behave that way in simulation?

Second, look in your design .map.rpt file, couple of sections:

16. Registers Removed During Synthesis

17. Removed Registers Triggering Further Register Optimizations

will tell you which register blocks have been removed, and give a reason why.
