General Description:
When I implement a design synthesized by FPGA Express, Design Manager fails during MAP and reports the following error:

"FATAL_ERROR:MapLib:basmmbdd.c:975:1.13 - remove_var, var 2 not redundant.
Process will terminate. To resolve this error, please consult the Answers Database and other online resources at http://support.xilinx.com"
