16 years agointerface stratixIV with an external ultrafast comparator
Hi everybody :) we need to interface ultrafast comparator- ADCMP572 - of analog device to a stratix4 device to perform one bit conversion. we expect that the comparator will ouput very short...

16 years agoI tried it with a Stratix II GX at 5Gbps. The GX/GT blocks in Stratix IV are similar, so it should work. I would have tried it with Stratix IV but to simulate you need to use ModelSim and I haven't done that yet, I always use the Quartus internal simulator.
In my simulation I may have been lucky to put the few bit values I tested in the right spot, but very probably you can sample any asynchronous data, just like FvM said.
