ltc2991 with Spartan-6 (FPGA)

I'm wondering if anyone has tried to integrate the ltc2991 to FPGA. (I am planning to read only the temperature from the sensor and my master will be Spartan 6)

I know it is communicated through I2C, however I have no experience with I2C on Verilog. 

If anyone has a start point or good suggestions?

Also, on page 4 of this datasheet, there are the times for I2C, but are those for standard mode (100kbit/s) or fast mode (400kbit/s)? 

Added link to the datasheet
