Impedance match and trace length

autodeskguest

Quick question:

 

Can the latest Eagle

 

1. Length (well, delay) match more than two signals simultaneously?

2. Create a controlled impedance trace?

 

I know that it can length match a pair if the signals are named

in a certain way, but I'm looking for a bit more than that.

 

Thanks,

    Hello Zoltan,

     

    I hope you're doing well. The differential pair routing in EAGLE has not

    improved much since it was originally implemented. 1 is currently not

    possible and 2 is possible, possible but you need to calculate the width

    and lengths you need to achieve a given impedance. You'll also have to

    be careful with how you layout the trace to simplify your calculations.

     

    Best Regards,

    Jorge Garcia

    I would also appreciate some better length matching, since I'm going

    face DDR RAM routing sooner or later.

     

    I have no experience how this is done in other CAD packages, so I have

    no idea what would be the most user-friendly way of implementing this.

     

    If anyone could make suggestions on how to implement it in the group?

  • I use this AR, it do it all and nice too!
