Timing Diagram
Timing diagram may refer to: * Digital timing diagram * Timing diagram (Unified Modeling Language) * Time–distance diagram A time–distance diagram is generally a diagram with one axis representing time and the other axis distance. Such charts are used in the aviation industry to plot flights, or in scientific research to present effects in respect to distance over t ... {{disambig ...

Digital Timing Diagram
A digital timing diagram represents a set of signals in the time domain. A timing diagram can contain many rows, usually one of them being the clock. It is a tool commonly used in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing diagram can help find and diagnose digital logic hazards. Diagram convention Most timing diagrams use the following conventions: * Higher value is a logic one * Lower value is a logic zero * A slot showing a high and low is an either-or (such as on a data line) * A Z indicates high impedance * A greyed out slot is a don't-care or indeterminate. Example: SPI bus timing The timing diagram example on the right describes the Serial Peripheral Interface (SPI) Bus. Most SPI master nodes can set the clock polarity (CPOL) and clock phase (CPHA) with respect to the data. This timing diagram shows the clock for both values of CPOL and the values for the tw ...

Timing Diagram (Unified Modeling Language)
A timing diagramOMG (2011)OMG Unified Modeling Language (OMG UML), Superstructure, V2.4.1 p. 546. in the Unified Modeling Language 2.0 is a specific type of interaction diagram, where the focus is on timing constraints. Timing diagrams are used to explore the behaviors of objects throughout a given period of time. A timing diagram is a special form of a sequence diagram A sequence diagram or system sequence diagram (SSD) shows process interactions arranged in time sequence in the field of software engineering. It depicts the processes involved and the sequence of messages exchanged between the processes needed .... The differences between timing diagram and sequence diagram are the axes are reversed so that the time increases from left to right and the lifelines are shown in separate compartments arranged vertically. There are two basic flavors of timing diagram: the ''concise notation'', and the ''robust notation'' . References External links Introduction to UML 2 T ...
