MAXII user flash memory simulation with I2C interface

Has anyone simulated MAXII flash memory with a I2C testbench?

If so, can you share me the testbench? Thanks.

    It sims fine, based on a very accurate stim that recreated a scope trace of a 24c01 transaction. It did not work in situ, though.

    I cannot get altufm_i2c (in Max II) to work in a real i2c circuit. 24c01 works in place. Altera is stumped. Anyone had luck with this function?

    I used the I2C megafuction in my design previously and it looks fine. I actually used a I2C kit to interface with the MAX II device to access the UFM. I am using this board:

    So far I didn't see any problem. You might want to try this as well. Good luck.
