we are developing an interface board for signal conversion. The incoming signal is sampled at 1.2 GHz (parallel input 14 bit). Two output channels are
planned to work at 150 MHz maximum. Arria II GX (EP2AGX65DF29C4) seemed to be the right choice using differential LVDS inputs.
But we cannot perform a verification simulation. Quartus II reports:
"Error: Quartus II software currently does not support the generation of timing analysis netlists for Arria II GX device family"
Since our time frame is rather limited, we need quickly a solution that works:
- is there an alternative for Arria II GX which is fully supported ?
- are there other sources to get detailed timing information for our netlist from ?
- how would you suggest to proceed further ?

I'm not sure that you need to use the Arria II GX devices. Do you really need the transceivers? The LVDS on the Stratix II devices operate at up to 1Gbps, and with DPA they are supposed to operate at up to 1.6Gbps.
I've used the LVDS at up to 1Gbps to interface to e2v's 8-bit 1GHz ADCs. Test data is here:
