Sorry to mention that the Stratix10 only supports up to Fast Mode of the I2c protocol.

For the Stratix10 I2C controller maximum speed is up to 400Khz.

This is mentioned in the Stratix10 TRM :

It is the same if you are using the I2C Host IP :

Hi Jingyang,

Please let me know -

Are there Open-Drain IO pads in Stratix 10 device that can run at 1Mhz or above?

Thanks,

Kiran
