Detailed Description
R
12. DUT Socket
The DUT socket contains the user FPGA, referred to as the device under test (DUT). The
DUT must be oriented using the P1 indicator on the board.
Caution!
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-4
device. When using BGA packages, do not apply pressure to the device while activating the
socket. Doing so can damage the socket and/or the device.
13. 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 8 and Table 9,
page 20.
