SMT700
From Sundance Wiki
The SMT700 is a Virtex 5 based PXIe card that has a Xilinx Virtex 5 LXT. SXT or FXT to implement the interfaces the board provides. .
The SMT700 is one of a new range of Sundance cards that includes a direct connection to SLB (Sundance Local Bus) compatible mezzanine card, without the need for a Sundance TIM. This enables a variety of cards to be added to a system, for example extra Ethernet ports, video in/out, High speed ADC / DAC etc. Data from these extra cards (along with data from the SMT700's own inputs - up to 1Gb/s Ethernet, 2.5Gb/s optical links, and RSL links) can be processed via the Virtex 5, or by another linked card or module.
Below are a few technical questions about the SMT700.
Q. Does Sundance provide HDL source to the Virtex5 LXT-50?
Yes.
Q. Are customers encouraged to do their own HDL development using this board?
It can be done, but needs a person with a lot of VHDL Experince. Diamond FPGA support in on the way and will make it easier
Q. Was the HDL source written in Verilog?
No, all in VHDL
Q. Are Xilinx LogicCores (such as PCIexpress and memory generator modules) used in the design?
Yes. The PCIe design is done using ISE11.1 or above.
Q. Can you provide the LXT-50 gate utilization report?
All depends on the implementation, but Sundance's IP-Cores takes less than 10%.
Q. If we need more gates than can be provided by the LXT-50, can Sundance build a board with a larger FPGA?
Biggest is LX110 now, but LX155 is potential option as well.
Q. Have any tests been done to show the maximum throughput from the SMT700 across the PXIe bus?
The bandwidth is 'full' speed on each lane and they are 2.5Giga bit per seconds.
Q. Does Sundance have any experience with implementing a XAUI interfaces with the SMT700?
No. Currently no plans to support XAUI. We use the Aurora IP-Cores for simplicity
