When using SDRAM Controller are SDC Constraints relative to SDRAM needed? 

 

Thank you

Yeah, unfortunately the Altera SDRAM controller does not seem to create timing constraints like the DDR2/DDR3 IP core does. 

 

I wrote some constraints for the DE0-nano SDRAM that are also valid for the SDRAM used on some of the other Terasic DE-series boards. 

 

See the example design and SDC file posted in this thread;

Thank you very much for the example. Altera should document better their ip-core.
