Hi Sneha,

Thanks for putting up the SDC file. I rectified a fundamental mistake I had made in not going through the Schematics properly. I am now able to establish communication. I am sending the I2C signals through the OUT_DVI_DAT and OUT_DVI_CLK ports marked in the schematics. The DVI Tx IC is configured through these ports. I had made the mistake of assuming that all I2C slave devices are configured through HSMC_SDA and HSMC_SCL ports just by changing the Device Addresses. However that is not the case.

Hi needed confirmation on one more thing - are you using a DVI monitor for display or a VGA monitor ? Because I dont see any DAC in the loop which might suggest it only drives a DVI monitor.
