    Hello there i am using pspice to make a simulation but i have a problem ( see the link down bellow ) the bus has no value while every other cable does

    Can you post your pic here? Pics hosted on other sites are prone to disappear.

    Because after some time the image will be no longer available from that site and this thread will make no sense, so it is better to attach everything right into the thread.
    Anyway, you are using next[14:0] at one place and next[14-0] at another.

    Have you looked at the actual netlist to see what it is showing?

    You might try deleting and redrawing the bus -- many schematic capture packages are over-defined and get internally inconsistent at some point such that the information used to draw the schematic on the screen is out of sync with the information used to netlist the schematic for simulation. About the only way to deal with that is to rip out the offending constructs and do them from scratch.

    thanks for your answer i deleted and redrew the next bus, then i deleted and redrew all the next cables and the bus but it still doesnt get any value. I uploaded the scematic, but it seems pretty chaotic

    :confused: doesn't the circuit need a voltage input source?
