pin delay settings in V16.2

purikku22

 hi all,

i have a design wherein we set the pin delay of BGA by using the pin property. But during serpentine wiring, the pin delay we add are not calculated automatically. What should i do enable the pin delay length we added?

 thank you.

    Hello,

    A couple things come to mind:

    1) Did you enable the Package Pin Delay DRC Checks.  Under the Setup Menu select Constraints > Modes and under the Electrical Options you will need to check the box under the Pin Delay section to include all Propagation Delays and Diff Pair Phase in the calcuations. 

    2) To take advantage of thes checks you will also need one of the higher tier tools to support this constraint otherwise they will be ignored.  In Allegro 16.5 you will need to enable the High Speed option during startup.  In Allegro 16.2 you will need to use the Allegro PCB Design XL license.

    Constraint manager will also show the headers for the Pin Delay as Yellow indicated that the rule is not enabled.

    Hope this helps,

     Thanks Urmil and Mike!

    I will try your solutions. I have a feeling that Mike answer is the problem. The last time I checked my design, I am using only a Performance Option. I will try it in the XL license that we have.

    Cheers! Have a great day

    Best regards,

    Eric
