System Bus Signal Simulations
Signals driven on the Pentium II processor system bus should meet signal quality specifications to
ensure that the components read data properly and to ensure that incoming signals do not affect the
long term reliability of the component. Specifications are provided for simulation at the processor
core; guidelines are provided for correlation to the processor edge fingers. These edge finger
guidelines are intended for use during testing and measurement of system signal integrity.
Violations of these guidelines are permitted, but if they occur, simulation of signal quality at the
processor core should be performed to ensure that no violations of signal quality specifications
occur. Meeting the specifications at the processor core in
Table 21
,
Table 23
, and
Table 25
ensures
that signal quality effects will not adversely affect processor operation, but does not necessarily
guarantee that the guidelines in
Table 22
,
Table 24
, and
Table 26
will be met.
