General Description: When I load a Virtex-E .prj file created by Project Navigator 3.1i with Service Pack 8 into Synplify 7.0.1, the following error is reported:
"Error: Device family not recognized."
The .prj file created by ISE 3.1i is similar to the following:
##-- Synplicity Inc. ##-- Synplify version 6.0. ##-- Project file h:\zliu\g4\modem_fpga\modem_xilinx_old\modem_top.prj. ##-- Generated using ISE.
This error occurs because the "-technology" option specifies "VirtexE" and not "Virtex-E" (with the hyphen) as Synplify 7.0.1 expects. (This issue was fixed in the 4.1i software.)
When Synplify 7.0.1 is used with the ISE 3.1i software, this error will only occur for the Virtex-E target family. All other components will work as expected.
To avoid this error, use Synplify 7.0.1 with the ISE 4.1i software; with the ISE 3.1i software, use Synplify 6.x.
