The following Virtex devices have the potential to create a high current draw when power is first applied to the device:
V100-ES, V200-ES, V300-ES, V800-ES, and V1000-ES
After the VCCint supply has risen above ~1.70V, this current draw will lower to the normal configuration current draw of <100mA.
This problem does not exist on the production parts.
Device Max Current Draw
This is not the case for Virtex-E engineering samples. These devices have no known
issues with current draw.
