    Hotswap in Vhdl using fpga

    hi,
    Does anyone have done hot-swap control in vhdl?

    Re: Hotswap in Vhdl using fpga

    Hi,

    Please be more specific.
    Hotswap often is used with power supplies. So how do you relate it to FPGA and VHDL?

    The hot swap controller is controlled by fpga through vhdl programming.

    Hi,

    As long as you don`t provide sufficient information it will be difficult to help.

    Ok, how about you mux different behaviours based on some external input.
    If pin is pressed(when something is connected) - Then do x
    When pin is depressed(when something is not connected) - Then do y

    How can this be?
    Usually a hot swap controller is on the slave board. And the hot swap controller controlls power supply behaviour.
    So how can a FPGA do something before it is powerd up?

    Still missing an explanation by OP.

    Re: Hotswap in Vhdl using fpga

    The OP doesn't talk about a FPGA controlling it's own power supply.

    I tend to ignore Edaboard threads if the OP doesn't manage (or even try) to explain the problem.

    Looks like this previous thread is related to the same problem http://www.edaboard.com/showthread.php?t=370400
