Hi, I am trying to use an OpenRISC architechecture for a project but need to implement I2C. Is there any I2C library and/or code floating around out there?

Did you look at the OpenCore I2C project by Herveille, Richard ?

It is a Wishbone interface to a I2C master. I'm in the process of using it for a FPGA to I2C I/O. My FPGA interface is a muxed parallel address/data with an ALE and CS, so it works fairly easily with Wishbone. I'm still in the hardware debug phase. The simulation and synthesis looks okay so far.

Can you guide me about how to get wave for I2C. i got sequence in modelsim but wave is not forming.

If you use this Wishbone controlled I2C core, you can just type "make" in the project directory and (assuming you have Verilator installed) it should build VCD files for you which you can then view with GTKwave.
