I'hv already checked on Saturn PCB Design tool. It checks a trace layer wise. Stripline and microstriplines are calculated individually. My problem is to calculate overall impedance (independent of layer stackup topologies). If a net has 4 microstripline and 3 stripline of different impedances for the same net, then what will be the actual impedance of the net ?

Ya, I checked allegro. it doesn't has the tool I'm looking for. Please tell me the Cadence tool name for impedance calculator if you know.
