Altera Corporation 71
EPXA10 Development Board Hardware Reference Manual
Power Consumption
Power consumption issues need to be addressed only if the board is
powered from a terminal strip and not the provided ATX power supply
adaptor. Altera recommends that you monitor the input current to ensure
that sufficient power is supplied. The power required by the board is
directly related to the following:
■ Number of interfaces used
■ Density and speed of the device
■ Population of the interfaces
The typical maximum current is 5.0 A, which can be exceeded if the board
is heavily loaded with many interfaces running at high-clock speeds.
PCI Cards
 Do not use 5-V-only PCI cards.
The PCI slots on the development board are suitable only for 3.3-V and
universal PCI cards. The keying slots on 5-V only PCI cards are not
designed to mate with the motherboard connectors, because the signalling
voltage on 5-V cards is incorrect for the development board.
Test Core Functionality
For implementing a test plan, Altera provides test cores with the
development board, which can be programmed onto the EPXA10 device
using the JTAG chain. Each test core tests one or more interfaces (push-
buttons, LEDs, switches, etc.). Diagnostic software is also provided to test
the board, the EPXA10 device, and its test cores, with results displayed on
a terminal.
