The maximum acceptable Flight Time is determined
on a net-by-net basis, and is usually different for
each unique driver-receiver pair. The maximum
acceptable Flight Time can be calculated using the
following equation (known as the setup time
equation):
T
FLIGHT-MAX
≤ T
PERIOD-MIN
− ( T
CO-MAX
+T
SU-MIN
+T
CLK_SKEW-MAX
+T
CLK_JITTER-MAX
)
Where, T
CO-MAX
is the maximum clock-to-out delay
of a driving agent, T
SU-MIN
is the minimum setup time
required by a receiver on the same net, T
CLK_SKEW-
MAX
is the maximum anticipated time difference
between the driver’s and the receiver’s clock inputs,
and T
CLK_JITTER-MAX
is maximum anticipated edge-
to-edge phase jitter. The above equation should be
checked for all pairs of devices on all nets of a bus.
The minimum acceptable Flight Time is determined
by the following equation (known as the hold time
equation):
T
HOLD-MIN
≤ T
