Variable Precision DSP Block for Cyclone V, number clock cycles for 1 multiplicaition

I went through the DSP section of hand book for Cyclone V. I did not find any specification on how many clock cycles for the multiplier to finish one multiplication. If any one here in the Forum can help on that I'd really appreciate it. I am assuming one clock cycle per multiply.

Thanks,

FZ

    The multiplier always completes in a single clock cycle. The multiplier itself if not a clocked part of the fabric - it's the registers around it that are clocked.

    Thank you for the quick response. That's what I thought. I just want to get a confirmation.
