You
can use the Stimulus function
to assert signal patterns or sequences of signal patterns on the PCIbus. (Caution: The signals will be asserted regardless of what else is
happening in the system.) This function can be extremely useful
for a number of different diagnostic tasks.
You can generate bus signals without having a system controller in
the backplane.

Hardware
Simulation
For example,
you may want to exercise circuits on a prototype board to diagnose a
problem. Using the Stimulus function, you can define a sequence of
signals to be asserted on the backplane without developing any software
and without any special hardware. |
Illegal Bus Conditions The
Stimulus function can also be used to assert ILLEGAL bus conditions to
test the response of a system to a variety of ILLEGAL conditions.
This can be very useful for verifying that a system will not crash
or malfunction due to extraneous interrupts or illegal bus activity. |
