Hi,
I'd like to simulate a very basic circuit which is a dc power supply, which schematic is here:

I'm stucked. I can't resolve 2 problems,

- Zener diode doesn't exist in ADS or i don't know how to get to it. In documentation is something about "zener" but in devices-diode the zener diode doesn't exist.
- How can I obtain a valid schematic since in ADS operation amplifier power supply nodes are not visible, and I can connect them to power supply "statically", I mean in above schematic in a link, the power supply is connected to other components, and it determines its behavior also. If I set the parameter for +15 or -15, the behaviour of the circuit doesn't influence on amp.

The OpAmp model in ADS is a high level system model which doesn't allow you to control/model all effects of a real amplifier. You need to get a better equivalent circuit model for the OpAmp to model effects like gain changes vs supply voltage variation etc. You might be able to get a Spice model for your part which you can import into ADS and use that instead of the built-in ADS model.
