    How to tell conformal that some input combinations do not occur Reply

    Hi

    I have a 3bit input signal which is coded such that it does not take the values of 110 and 111. How will I be able to put such a constraint on the input pins in conformal?

    Thanks
    Prasad.

    Hi Masood,

    I tried contacting the support guys, but for some reason they were not ready to resolve the issue. I would try again with them, but if you are having any app notes or any other source which would help me please mail to nss.prasadaddagarla@gdatech.co.in

    Thanks

    Prasad.

    Hi Prasad

    Preventing the first 2 bits from being 11 is good enough in your particular case. For that, use 'add pin constraint zero_one_hot bit2 bit1'. No need to constraint bit0.

    Hi Chrystian,

    You are right. I have already employed that with this particular case. But I am curious to know what can be done if such a solution is not available. I am pretty sure that somewhere and somewhen I would need it!

    Thanks
    Prasad.

    Hi Prasad

    On Sourcelink, search for "constraint" under Conformal (do not include Conformal Constraint Designer). Results 1, 2, and 4 are what you are looking for.
