4.1i MAP - "FATAL_ERROR:MapLib:basmmbdd.c:975:1.13 - remove_var, var 2 not redundant..."


Keywords: ISE, 4.1, FATAL, ERROR, MapLib, basmmbdd, Virtex, 975

Urgency: Hot

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"


To work around this problem, set the "Preserve Hierarchy" box in the synthesis options.
