[ibis-interconn] MCP Discussion questions for today, plus scaling

Here is a simple slide set to frame our MCP discussion for today.


Also, here is a simple set of explanations answering Arpad's IBIS-ISS question 
on scaling:

Scaling is through an "S parameter" (yes, unfortunate name), similar to the M 
parameter for device circuits.  Scaling is activated by using an "S" on the 
instantiation line of a subcircuit, as in:

Xmycircuit in out circuit_definition S=1u

Separate .option statements are used to control whether scaling is active or 
not (meaning, does S refer to a user-defined parameter or actual scaling) and 
what the default scale of the subcircuits in the netlist will be.

If scaling is not active, S is assumed to be simply a user-defined parameter.

Scaling is cumulative, so scaling an already-scaled subcircuit will compound 
the effect.
