Questions relating to designing PCBs

Hi,

I'm using eagle to do schematic entry. I'd like to use the schematic to export a netlist for spice simulation, as well for PCB layout in eagle.

There can of course be some differences between the schematic required for layout and the schematic required for simulation. Notably devices which will get connected via pads on the PCB need to be present in the simulation netlist. eg: power supply, mechanical switches, etc.

Does anyone have recommendation for how to handle this? Do I need to maintain two schematics? I'm mostly interested in eagle-centric answers but also curious about how other tools may handle this.

Thanks,
James

Another question: I assume for low speed PCB stuff it is not necessary to do any parasitic extraction from the layout? Are there any tools which support this?
