Sundance SMT166 - Manual (Page 5)

1 Introduction
The SMT166 is an SLB Platform designed around two Xilinx Virtex-6 FPGAs. It can
receive up to 4 SLB mezzanine modules and one TIM or SLB base module. The
SMT166 shows a symmetrical architecture in order to suit needs for 2
n and scalable
systems.
Each FPGA is responsible for routing data to/from half of the SLB connections on
the board.
Connections (parallel and serial) between FPGAs are available for inter FPGA
communications.
Each FPGA is coupled with 2 banks of DDR3 memory, 32-bit wide and able to store
up to 256 Mbytes of data (per bank) at a maximum rate of 4.2 Gbytes/s.
FPGAs can be programmed using a simple Xilinx USB Programming Cable (JTAG)
whilst in the development phase. Final applications can be stored into an on-board
flash memory. There is one flash for both FPGAs in order to avoid initial conflicts
while FPGA are being programmed. The flash memory can also be accessed from a
host PC through a USB link. Equally, the flash on the master module can also be
accessed from the host though the USB (through Comport 3). A CPLD is responsible
for routing and managing accesses. Configuration selection can be made via a DIP
switch. Host accesses can be initiated by the SMT6002 software package.
Two types of cable PCIe connectors will be available on each half of the board, the
first one for a 4-lane PCI Express link and the second for a 1-lane PCI Express link.
They can be used as a link to a host system or in order to make this SMT166
platform scalable and cascade several of them, keeping the need for only one host
connection. All Express links are Gen1.
Two SATA 3.0 links and two 1Gigabit Ethernet links are available for fast transfers
to/from a remote host or an external storage unit.
SLB connectors are manufactured by Samtec. The data connector is part of the
QSH/QTH family and the power connector is part of the BKS/BKT family.
The SMT166 receives a standard 24-pin ATX power. A switch on the board is
available to turn on or off the ATX power supply used.
An optional clock synchroniser and clock distributor is available. This allows
generating clocks for SLB mezzanine modules.
