Cyclone V sleep mode

Hello all,

Is there a way to put a Cyclone V GX FPGA into a sleep/hibernation/low-power mode?

Our design will involve the system being idle for long periods of time, and we're hoping to keep power draw at an absolute minimum when it is not active.

Thank you!

    There's no such mode. However, if you stop the clock you'll save a lot of power.

    If you want to save even more power for "long periods of time" turn the power off to the device. Then power it up and let it boot when you need it.

    Cheers,

    Alex

    Ah, okay, I must have been thinking of a different device that had that mode available.

    I think shutting off power will probably be my best bet, I think the config time for the Cyclone V is not very long, a few ms.

    Thanks Alex.

    Perhaps a few hundred ms, but not long either way.

    Cheers,
