I have noticed that some Motorola products (the MPC2605 L2 cache for
instance) specify AC timing using a 50 ohm transmission line instead
of the traditional 50pF lumped load. This makes it difficult to do
"net-loading" analysis the way it was done in the past, comparing the
sum of the input capacitances, Iil and Iih of the inputs on a net to
the driver test capacitance, Iol and Ioh.
