What is a timing diagram in UML?
In UML, the timing diagrams are a part of Interaction diagrams that do not incorporate similar notations as that of sequence and collaboration diagram. It consists of a graph or waveform that depicts the state of a lifeline at a specific point of time. It explains the time processing of an object in detail.
What is the purpose of timing diagram?
Timing diagrams represent timing data for individual classifiers and interactions of classifiers. You can use this diagram to provide a snapshot of timing data for a particular part of a system. Timing diagrams use lifelines from sequence diagrams, but are not directly correlated to the sequence diagram in Rhapsody®.
What is timing diagram example?
Timing diagrams are UML interaction diagrams used to show interactions when a primary purpose of the diagram is to reason about time. Timing diagrams focus on conditions changing within and among lifelines along a linear time axis.
What is the use of use case diagram?
A use case diagram is a graphical depiction of a user’s possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses.
What is T1 T2 in timing diagram?
Step 1: During T1 state program counter places the 16-bit high order memory address on the address bus, low order date on the data bus and ALE signal goes high for address latching. Step 2: At T2 state, The control unit sends the control signal RD = 0 to enable the memory chip to read opcode from memory.
How does a timing diagram help a user?
Timing diagrams show how long the certain processes take. From this data, users can know which steps in a process take too much time, and what needs to be streamlined for the system or piece of software to operate more efficiently as a whole.
What are the bright links on a timing chain?
Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.
What do you need to know about timing chain replacement?
Also verify that your model is equipped with a timing chain and not a timing belt. These two parts perform the same task, but replacing them can be quite different. This procedure is only for replacing a timing chain. Clean the engine with the proper degreaser thoroughly before beginning.
How do you change the timing chain on a water pump?
Remove the belt. Once tension is released, the belt should slide off of the other pulleys easily. Remove the heater hoses from the water pump. If your model has heater hoses attached to the water pump, loosen the hose clamps with a screwdriver and slide them back onto the hose. Wiggle the hose and pull it off of the water pump.

Step 2: In the white sidebar, click on Software Development. Then, click on the UML Modelling box that appears near the top of the screen. Step 3: Choose a template, or click on the UML Modelling box with the “ + ” to open a new document. Step 4: The symbol library can be found to the left of the screen.
How to draw a timing diagram in UML?
Put one life line with a number of possible states above the other vertically, and the passage of time (say in seconds) horizontally. Each object has a set of possible states. The state will be changed over time indicated by the timeline. Model the messages sent from one object to another can be depicted using simple arrows.
