Simple I2C slave model (IO expander)

    I know that this has been asked for several times, but I haven't found
    a satisfying answer yet.

    Has anybody got a simple vhdl model for an I2C slave ? All I need is
    to Read/Write some IO bits. I would like it to be as small as possible
    (20-40 Xilinx CLBs or Altera LCELLs).

    Thanks for your help,

    Alex

    Not exactly what you want but parts of the I2C core at www.opencores.org
    might help you
