i2c cpld

Hi ,
I want to send serial eeprom data to CPLD/FPGA in I2C bus .
My component is AT24C16 and AT89s52 and FPGA

There are two way I could think of :
Way 1:So need to write a I2C HDL code let FPGA directly read AT24C16
Way 2:Use AT89s52 to read AT24C16 then write to FPGA by I2C bus .

Coudl you help to get reference design or HDL code


very thanks a lot !!

I am also have the same request.

You can see XAPP333 in xinlinx appnotes.
(Search in xilinx web site ).

This is the only code.

I have a further question on how to detect High 'z' in I2C bus. see my question.
