Apart from using a suitable logic level, I2C requires also strong pull-up resistors and a bidirectional level-translator at least for SDA. This isn't a matter of using a particular FPGA I/O pin but of a right hardware design with the HSMC to Santa Cruz adapter. I can't see from your post, if the I2C requirements are met.
