ROACH2 Issues...
FPGA choice
Form factor
Processor + bus interface
Monitoring of temperatures and voltages/currents
Power supply
ADC interface
Number/type of memories

FPGA choice
Virtex6

Form factor
ATX I/O area is limiting 1U height is important Cooling

Processor and bus interface
32 bit would be “nice”... how “nice” exactly? AMCC availability? Changing? ARM??

Monitoring
Temperature Fans Voltages Currents Remote access?

Power supply
AC or DC?

ADC Interface
Z-DOK likely best choice for now Serial I/F would need too many transceivers

Memories ...
QDR II+ 36 bit or 18 bit? 2, 3, 4 or more?
DDRn Can do 4 x QDRII+ 18 bit wide + DDR with
SX475T

10 Gigabit Ethernet
Time to go SFP+ 6x … 8x? 1 Gigabit from FPGA

Testing and programming
Suggestion for a single USB device interface using FTDI USB-JTAG bridge
Eval kit will be tested with ROACH Production testing via JTAG

General interfaces
I²C USB Host (1 x ?) Serial Ethernet control and monitoring
10/100 IEEE 1588

One possible configuration
1 DDR DIMM 4 x 18 bit wide QDRII+'s 2 x Z-DOK 8 x SFP+ Diff GPIO (40 pair) 32 bit processor bus 2 x 1G ethernet from FPGA Leaves 34 “spare” I/O's
