is on the top (component) side of the carrier board while “A” is on the bottom
(solder) side. Connector “gold finger” numbers increase with distance from
the bracket end of the printed circuit board.
Refer to the PCI Express bus specification for additional information on the
PCI Express bus signals.

Notes (Table ):
1.
Asterisk (*) is used to indicate an active-low signal.
2.
BOLD ITALIC Logic Lines are NOT USED by the carrier board.
3.
+3.3Vaux power to AcroPack is not used by the carrier. Contact Acromag to
3.3Vaux power to the AcroPack module. The carrier pr3.3V
power to the module.
JTAG Programming/Debug Connector
A JTAG programming/debug connector is provided for developing applications
that use Acromag’s FPGA AcroPack modules. See reference designator P3 in
Error! Reference source not found.
. This is a standard 14-pin Xilinx
programming header for connecting a Xilinx Platform USB II programming
device (or equivalent). The pin assignment for P3 is shown in Table . A CPLD
on the carrier is included in the JTAG chain. The Xilinx Vivado tools can detect
the presence of the CPLD in the JTAG chain and skip it when accessing the
FPGAs on the AcroPack modules.
