adding a control signal to the SOPC

i need a single-bit control output from the NIOS. currently, i have created a new single-bit PIO. however, this output signal will not hold as a logic high. instead, it rises and falls with the clock signal. is there some "output" component or something from the NIOS that will hold the signal high until it is set low again? (it could be that there is another problem with my design...let me know)

    Hi cryinlion85,

    This sounds like your pin assignments are incorrect ... i.e. you may have a few signals

    mapped to the wrong pins.
