Hi,

For LPM_MULT IP-Core asynchronous clear, clock enable & synchronous clear are have optional support so either you comment those signals or instantiate an LPM_MULT function without the squaring function and use the same signal for both dataa and datab inputs since in squaring operation multiply 'dataa' input by itself.

refer the below solution & user guide,

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
