[Altera_Forum]

Hi all, 

as part of my finalproject in my electronic engineering studys, i am supposed to have a NIOS2with multymaster, multyslave I2C components. On the SPOC i sawthere is no such interface. Does anyone have a verilog/vhdl code for such aninterface? Can someone give me help with what direction should i carry on myresearc regarding this issue?

Thanks for your help. I saw this page but to my best understanding, it works with wishbone, and I think i need for the NIOS Avalon. 

Am I right? if i use a code from opencore do i need to publish my code?

Hi, 

does this reference design not fit your needs?  http://www.altera.com/support/refdesigns/sys-sol/indust_mil/ref-i2c.html  Greets

Thanks. Do i get there the design verilog/vhdl code? 

I did not quite understand what does this I2C Controller Reference Design mean. Is it a board? Is it a SW tool? Can I play around with the code? Many thanks in advance.

Hi, 

 a reference design is a vhdl/verilog design you can use in your application for free.  Greets
