Hi Hub !
1. in your uSimmics simulation you have t=0 um in Subst1, change that to some thickness t=35um
2. you have different widths, lenghts and substrate thickness in your simulations, uSimmics vs ADS, 10 mil = 0.254mm, 1000mil = 25.4 mm, 1550mil = 39.37mm
3. In your ADS simulation you have used ML1CTL_C, I think that this is some kind of coupled line model, If I remember the ordinary model is MLIN and MSUB if you wnat to do a comparision with uSimmics.
