When I attempt to set a value for voltage using a CPLD design via ISE, the following error occurs:
"FATAL_ERROR:SpeedCalc:Dly_ReadSpdFile.c:795:1.12 - The version number of the speed file (24832) indicates that it is newer than the highest version this software can deal with (46). This means that you have a new speed file and old incompatible software installed in this environment. You must either upgrade your software to the newest released version, or get a version of the speed file which is compatible with the release of the XILINX software you are using"
