may be guaranteed by design rather than by testing. The clock fre-
quency may be changed at any time during the operation of the sys-
tem as long as the clock edges remain “clean” (monotonic) and the
minimum cycle and high and low times are not violated. The clock
may only be stopped in a low state.
