    Hi ranjeet,

    I tried your suggestion of symmetric compensation but it is also not working.

    Hi Sanjeev,

    As you told I have set optimum bitrate of layout to 40Gbps..In output I am getting Q factor of hardly 2 and getting any of one output either I or Q channel. When I monitor constellation diagram then it is not proper all phases I got in one quadrant only.
