8.2i Virtex-4 MAP - Design with DSPs crashes after message "mapping design into LUTs"

Description

My design containing DSP components crashes during the MAP phase, after the following message: 

 

"mapping design into LUTs" 

 

NOTE: This Answer Record is a potential match for any case that meets the above criteria before version 8.2.3i. There can be other causes for this same failure mode. For links to other known issues and general information on debugging MAP crashes, see the Master Answer Record (Xilinx Answer 23363).

Solution

This problem has been fixed in the latest 8.2i Service Pack available at: 

http://www.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is 8.2i Service Pack 3. 

 

Meanwhile, to work around this issue, set the following environment variable: 

 

Windows 

SET XIL_MAP_NO_DSP_AUTOREG=1 

 

Linux and Solaris 

setenv XIL_MAP_NO_DSP_AUTOREG 1 

 

For more general information about setting ISE environment variables, see (Xilinx Answer 11630).
