currently i'm working with spartan 6 and i must use the DDR3 to read and write , i used the MIG , but a have several question to ask whom work with this tools core generator :
First of all : i read documentation i find that i can generate my design by using the example design which i have some instruction like create.bat , So
if i generate the Core why i must generate the project with Create.bat ??
also i'm trying to modify this parameters but i don't know how which value must be added knowing my user frequency is 27Mhz and the DDR3 800Mps that is all i know for the moment ,
Any help please ?
