Make a differential pari\n2. Tune the length of the one track\n3. Tune the length of the other track of the same pair is in 2. (It may matter to make sure that they are not of equal lenght)\n4. Use the tune differential pair lenght tool on that pair\n\nExpected result:\nit would in a sensible way override the tuning doine by the individual tunings\n\nResult observed:\nSome of the track from the previously made meanders become straight lines, that does not in any sensible way seem to be impedance matched anymore. See the attached screenshot.  A pcb to test on is attached.\n\nAlso some other wierdness where the tracks will be invisible occours on attemps to tune after the above steps."}}
