Sine wave to Digital clock..

I know this might be a strange question coz sine wave can be used as a clock, but I really wanna know the best to cut my sine wave from both sides to produce a digital clock. I tried using veri...

You must do this externally to the FPGA with something like a Schmitt trigger or other circuity

FPGA's are digital only e.g. LVTTL, CMOS Levels etc
