    what is the usage of the port in the fpga?

    Hi All

    In FPGA, there have ports used all the time.

    I am wondering what is the purpose to use port and what function can it provide?

    Can anyone give some reference or explain it here?

    Thanks

    Hi,

    Can you be more descriptive?
    Which port are you talking about? Please refer to a FPGA datasheet with section and page.

    In general, what does port mean in FPGA? what is it used for?

    Thanks

    Hi,

    Are you referring to port in VHDL? If so they are the inputs to and outputs from the system you're implementing. So you use port to specify your interface to the system you're implementing, their directions (whether input, output, both, buffer, etc), their data types and number of bits that they have or that you need.

    There's much more to it but this is basically what you have to start with.

    In FPGA, there have ports used all the time.
    Where? Please give some good quality reference to support your claim!

    In general, what does port mean in FPGA? what is it used for?
    I would say that a port in FPGA in general has no meaning.
    Pins have meaning in FPGA, which are the physical leads that can be soldered to a PCB, something which you can touch.

    The term port is more often used in RTL (VHDL/Verilog), which indicates a group of in, out or inout signals. When a design is done with RTL, the ports indicate the peripheral signals using which the design interacts with the outside world.

    A group of ports can be assigned to a group of pins in an FPGA to perform a specific function (e.g. - HDMI port).
