done. The component test guarantees that all timings are met with minimum clock slew rate
(slowest edge) and voltage swing. The design must guarantee that minimum timings are also met
with maximum clock slew rate (fastest edge) and voltage swing. In addition, the design must
guarantee proper input operation for input voltage swings and slew rates that exceed the specified
test conditions.
