How is a timing diagram different from a sequence diagram?
The most notable graphical difference between timing diagram and sequence diagram is that time dimension in timing diagram is horizontal and the time is increasing from left to the right and the lifelines are shown in separate compartments arranged vertically.
When to use a greyed out section in a timing diagram?
There can be several definitions associated with a greyed out section in a timing diagram, however it is most often used in the event where the processing system simply doesn’t care what the values are.
Where do you find the clock in a timing diagram?
As a timing diagram specifically deals with the sequencing of steps, you’ll invariably find the clock signal at the very top, because that is what governs the rise and fall of your signalling empire.
When does a timing diagram become a hindrance?
This is typically where a timing diagram goes from being a help to being a hindrance. If you’re lucky, the timing diagram designer will have found a way to cram as much text into the page as possible. If you’re not lucky, it will only reference numbers that lead to footnotes at the bottom of a table four pages before or after the diagram itself.
The most notable graphical difference between timing diagram and sequence diagram is that time dimension in timing diagram is horizontal and the time is increasing from left to the right and the lifelines are shown in separate compartments arranged vertically.
Which is better, timing or sequencing, which comes first?
He was definitely more focused, but then I noticed that if he focused on the timing, he had a lot of difficulty remembering and focusing on the sequence, and vice versa – if he tried hard to get the sequence right, his timing really deteriorated.
Which is the third message in the timing diagram?
There is a third message, “start pump”, which the client sends to the pump service when the level is too high. The second message has no response. The diagram shows three actions: reading the sensor, deciding whether the pump must be started, and starting the pump.
How is the lifetime of a module represented in a timing diagram?
In a timing diagram, the lifetime of a module is represented by a vertical line, with time increasing down the vertical axis. The following example illustrates the use of a timing diagram for a sewage pumping system. The label at the top of a timeline names the module (pump controller, sensor service, and pump service).
