Abstract
A signal monitor device that detects a signal propagating on a signal line and that generates a timestamp when the signal is detected. The timestamp may be used in a variety of applications including measuring the propagation delays on signal lines and determining the timing in a system.
Claims20
A signal monitor device that detects a signal propagating on a signal line and that generates a timestamp when the signal is detected.
A method for signal monitoring, comprising:
- detecting a signal propagating on a signal line;
- generating a timestamp when the signal is detected.
A system, comprising:
- a set of signal monitor devices that generate a set of timestamps in response to a set of signals propagating on a set of signal line;
- device that obtains the timestamps from the signal monitor devices via a network, the device having a clock that provides a time base for evaluating the timestamps.
