UG116 mentions that ISE and Vivado can both create the SEU report that provides the DVF factor.
How can this be done?
ISE:You will need to Import your ISE project into Planahead and then run the following tcl commands
report_power -verbose -file power_report.txt -seu C:/test/seu_report.txt
This functionality is not yet supported. It is planned to be included in a later release. 2014.x
