I'm Protel DXP user and need some info about Impedance-Controlled Routing. I'm at my first experience with this routing constraint, and this
make things more difficult to me too of course...
I understand I can set the min - max preferred characteristic impedance value Z0, in the Signal Integrity Rules, and this value will be used to calculate the track widths by the formulas in the Layer Stack Manager, with all other parameters entered about materials, dielectrics and thicknesses. But where is that Z0 is related to signal frequency? In my example: I need wires of 50ohm impedence with signals 100MHz max. freq. How can I set up things to get my goal?
And the formulas that are shown in Layer Stack Manager can be modified or adjusted to get different/better/more specific calculations?
