I2C Level Shift use PLD

--- Quote Start ---

You cannot easily use an FPGA to perform I2C level shifting, since it needs to act as a bridge (since there would be two different I2C buses), you're better off using devices like the LTC4313

that page has a link to Linear Technologies other I2C buffers, i.e.,

Thanks Dave for advice. I know it's NOT easy. Normally, I2C level shift is used for these condition. I just want try to remove this part from BOM. Any one has idea about it. Thanks!
