ERRORlace:293 - Mapping error in virtex 6 fpga
Hi all,
I am developing a design using Virtex 6 (XC6VLX240T-1FF1156). In this design Im cascading two inputs using DSP48 Slices. There are a total of 768 Dsp slices present out of which Im using 512 of them. In the user guide it was written that only 96 DSP Slices can be cascaded using the inputs A and B in one column. Hence the design was written in such a fashion. Currently Im getting an error at the Mapping stage as follows:
When i look into the Mapping report there is a detailed analysis as follows:
I have tried implementing the design with and without area grouping constraints, but with no avail. Please help!!

ERRORlace:293 - The following 96 components are required to be placed in a specific relative placement form. The required relative coordinates in the RPM grid (that can be seen in the FPGA Editor) are shown in brackets next to the component names. Due to placement constraints it is impossible to place the components in the required form.
