Please help me ......SDRAM DE2

system:

De0 - SDRAM (A3V64S40ETP G6);

Quartus II 11sp1;

QSYS;

Nios II EDS (eclipse).

The lack of parameterization in the memories is a common flaw found in the Terasic kits. The realization of this is visible when looking up the forum for answers from Altera.

I'm trying to implement a simple Nios II SDRAM to have a little more memory.

I tried with the parameters of the "Embedded Peripherals IP User Guide", but nothing works. The frequency used in PLL as setting 50 MHz (20 ns) because Tac = 17ns.

I tried to set it to 100MHz (Ph-3rd) according to the datasheet "A3V64S40ETP G6", but has problems of ELF. I found many settings that were placed without concern for a frequency of operation and specification of memory.

So, I would like the configuration parameters of the SDRAM.

SERENETY NOW!!!!
