specification, the accuracy will suffer. Specifically, the
Pentium Pro processor die will consume more current at
high voltage and less current at low voltage while the
SPICE model does not exhibit this behavior. Therefore,
bear in mind that while this model can be used to
accurately model a system that meets or exceeds the ±5%
voltage requirement, it cannot be used to accurately
describe how far out of specification a poorly designed
system lies.

Power Distribution Model
This is the HSPICE format power distribution model for
a socketed Pentium Pro processor. The schematic is
shown in Figure 30. Note that the last line of the model
includes “R 73.9NS”. This commands the simulator to
continuously repeat the last portion of the waveform
from time 73.9nS until the end of the simulation.
