For Virtex, do any issues exist regarding the order in which you power up the different voltage supplies?
NOTE: For information on Virtex-E power sequencing, please see (Xilinx Answer 10129).
There are no restrictions on the order of VCCO, VCCINT, and VIN power applications. For more information, please see the Virtex Data Sheet -> Module 3 Electrical Characteristics -> DC Characteristics:
http://www.xilinx.com/support/documentation/data_sheets/ds003.pdf
Device lifetime information is provided in the Quality and Reliability report:
http://www.xilinx.com/support/documentation/user_guides/ug116.pdf
(Check the Quarterly report for Device Hour.)
If, after power-up, the VCCINT is lost, the I/Os will go into a 3-state condition and return to their pre-configuration state. If VCCO is lost to Banks 2 and 3, the device will also lose its configuration.
