Help how to use avalon interface

Hi everyone, 

I'm using a DE1-SoC board. 

I'd like to transfer data from FPGA to HPS and I have to use the avalon interface but I never used this interface. Anyone can have some document or example? 

My project consist in acquire data from the FPGA pins and then send data in a SDRAM that is shared with the HPS and finally send to the PC throught the ethernet interface. 

 

 

Anyone can help me? 

 

Thank you 

Gianluca

The best way to understand the Avalon interface is to use the BFMs to exercise your components or your design. See the tutorial at the top of this page:
