I am currently developing on the Altera DE4 and so far i have only used the On-Chip Memory for my nios processor. but now i am running out of space as my project is getting bigger. I would like to start using the SSRAM that the DE4 offers. I am just not sure how to use it with the SOPC builder. I understand that i will probably need a tri-state bridge but i not sure if i need another block or if not how am i going to configure the tri-state block.
