That=E2=80=99s one way to do it. There are others.
For a flat design, you can have a simulation page that injects power and =
signals into named nets in the pages representing the board design. Just =
leave that page out when building your layout netlist.
Another way is to give the connectors on your board spice-prototype =
attributes representing power and signal sources.
The spice-noqsi back end is basically a macro expander for injecting =
attributes into SPICE cards. How that works in your flow depends on how =
you write your prototypes. The default prototypes mimic the spece-sdb =
back end, but you need not go that way.
