Power Supplies
The PCI specifications state that the maximum power allowed for any PCI board is 25
Watts, and represents the total power drawn from all power rails provided at the
connector (+5V, +3.3v, +VI/O,+12V,-12V, +3.3Vaux). The expansion board (in our
case the TIM carrier board and the TIM modules) may optionally draw all this power
from either the +5V or +3.3V rail.
Nevertheless, it is anticipated that many systems will not provide a full 25 Watts per
connector for each power rail, because most boards will typically draw much less
than this amount.
For this reason it is recommended that you analyse the total FPGA device power
before implementing your design in the FPGA.
This will tell you if you need to use the external power connector provided on our
carrier boards. (Like the SMT310Q carrier board)
