Using SDRAM with a peripheral

[Altera_Forum]

Hi,  

I am trying to connect SDRAM to my peripheral device directly and I read the postings on the forum which says I can use "user logic" to connect to SDRAM controller. I tried writing my user logic but its not working correctly. I am working on DE2 development board. Has anyone implemented anything like this? if yes, please let me know how to implement it.  Thanks, sony

Can you be a little more specific....Are you using a IP core controller without an avalon interface; or are you trying to break out the avalon bus to some off-chip controller?

Hi Daniel, 

I am not very sure how to answer your question but I will try with my limited exp. I was thinking that I can use the SDRAM Controller provided in the Quartus and write a user logic which will act as a master to the avalon bus and the SDRAM Controller will be connected to the slave and I can generate the necessary signals. Please let me know if it can work like this.  also I want to include the nios processor in the design, so basically I have nios and User Logic as master to the avalon bus and SDRAM controller is connected as slave.  Please advice  Thanks, sony
