Timing variation measurements |
摘要 |
Measuring timing variations in a periodic signal includes producing trigger signals in an integrated circuit in response an externally-generated periodic signal. First and second oscillation signals are generated in response to the trigger signals. A first count of the number of pulses in the first oscillation signal from occurrence of the first oscillation signal until the oscillation signals are in phase and providing a second count of the number of pulses in the second oscillation signal from occurrence of the second oscillation signal until the oscillation signals are in phase.
