When I run a design with a PL4 core on my PC in ISE 5.1i Service Pack 3 MAP, the following error is reported:
"FATAL_ERROR: Pack:pktbafirewall.c:138:1.1 - Failed to create device helper Process will terminate. To resolve this error, please consult the Answers Database and other online resources at http://support.xilinx.com. If you need further assistance, please open a WebCase by clicking on the "WebCase" link at http://support.xilinx.com."
This error does not occur on UNIX machines.
If you are using the "-timing" switch in MAP, try running MAP without using this switch.
If you are running "imlement.bat" (which is provided with the PL4 design example), please remove the "-timing" switch.
If your design cannot meet timing after the "-timing" switch is removed, please contact Xilinx Customer Support at:
