Hi All. Say I have a PCB layout with RF Microstrip traces on it. Although the Allegro PCB designer is able to show trace impedance (50ohm in my case) by certain stack-up and trace width, am I able to do sort of simulation and maybe check S11 for my layout before sending it to fab? If so, what kind of tools (ADS?) I can use and would you please kindly share some guidance documents with me?
