I am trying to choose an FPGA development kit for a lab.
We are working on projects which have input signals with periods of 10 nanoseconds. The application itself is relatively simple but involves the sending of start and stop signals to multiple (2 or 3) devices and receiving status inputs of digital signals.
Is there a particular product that is recommended?

With that little input:
If the signals are synchronous to an external clock that you can feed into the FPGA, things are (relatively) simple and you could use Cyclone iV, Cyclone V or MAX 10 devices. If they are asynchronous it is a different ball game, you need to synchronise these signals with a fast clock, which needs to be about 4 times faster than the smallest pulse width you have to detect, in this case half the period or 5 ns. Which dictates an internal clock of around 800 MHz, which are theoretically possible with Stratix IV and V devices, but will take careful design to achieve timing closure.
Now if you explain your project(s)a bit more and perhaps add a block diagram we (I am taking the liberty to speak for other contributors too) can very probably give better directions.
