19. DUT Socket
The DUT socket contains the user FPGA, referred to as the Device Under Test.
The device must be oriented using the P1 indicator on the board. Failure to insert the
device to the proper orientation can damage the device. To avoid pin damage, always use
the vacuum tool provided when inserting or removing the Virtex-II device. When using
BGA packages, do not apply pressure to the device while activating the vacuum tool lever.
Doing so can damage the socket and/or the device.
20. Pin Breakout
The pin breakout area is used to monitor or apply signals to each of the DUT pins. Headers
can be soldered to the breakout area to use with certain types of oscilloscope probes, for
either connecting function generators or wiring pins to the pin breakout area. Clocks in the
pin breakout area that connect to the DUT clock pads are shown in Table 12.
21. User LEDs (Active-High)
There are eight active-high user LEDs on the board. Before configuration, the LEDs reflect
the status of the configuration mode switch. During configuration, the LEDs are in a high-
impedance condition. After configuration, the LEDs are available to the user and reflect the
status of pins D0-D7 (corresponding to LED 0-LED 7). The LED assignments are shown in
Table 13.
