Eagle Impedance Control

Former Member

Does eagle contain some sort of impedance calculator for high speed systems (USB,DDR3,etc) and/or auto-router functionality that incorporates impedance control?

Best Regards,

    Hi Osi,

     

    It doesn't include an impedance calculator. However there are facilities

    for manual length matching(the autorouter can't add meanders, at least

    not yet). You could use something like the Saturn PCBTools calculator to

    determine the necessary length and width for a certain impedance and

    then use the differential pairs facility in EAGLE to implement those values.
