Hi guys, I want to save data in the SDRAM and afterwards to read out the data from the SDRAM. For my project, I used the Qsys and implemented the components afterwards in my VHDL code. Wh...

SDRAM is a complex chip that requires special logic to operate.

It needs an external refresh mechanism to keep it going, I think this aspect is not in your code.

what he's saying, you need a memory controller, thus can be integrated by using IP Cores, otherwise the Memorycontent wont be safed, because s"D"ram is dynamic, which means, bits are stored to capacitators which must be refreshed. (by a controller.)

I consider right now using the onboard DDR3RAM, because its faster, but cant get any IP wordking till now on Quartus 17.1 ...
