Hello,
Thank you for submitting your question in Intel Community.
I'm Adzim, application engineer will assist you in this case.
You need a module that can communicate with the memory controller (EMIF IP) to act as a driver or traffic generator.
This driver should provide the required signal to memory controller in order to perform the memory transaction.
You may refer to Avalon Interface Specifications that provide some details about the avalon transfer: https://www.intel.com/content/www/us/en/docs/programmable/683091/22-3/transfers.html
You also can refer to EMIF example design that can be generated from Quartus.
You can refer to the link below on how to create an EMIF example design.
