[Fpga-synth] New FPGAs

[Nicholas Gregorich]

The DDR hard IP is interesting, closing timing on high speed DDR designs 
is not trivial. Along with the announcement from Altera today (high end 
Stratix IV GT with 11.3 Gbps transceivers and mid range Arria II GX with 
3.75 Gbps transceivers and PCIe hard IP) its obvious that high speed 
transceivers are currently driving the FPGA market.
