Trace Window
In the Trace window choose the output mode Fixed position for cyclic update.
As a result, the window contents are no longer updated with each new arriving
message, rather they are only updated cyclically. You may need to select a
longer update time.
Data Window
If you have configured many signals in the Data window, you should choose the
cyclic refresh mode here (Configure Timer entry in the Data window's popup
menu) and enter a cycle time of maximum 500 milliseconds. The window is then
only updated cyclically which saves on computing resources.
Graphic Window
If you have configured many signals in the Graphic window, you should choose
a relatively large user-defined refresh (200 ms to 2 s) in the Measurement
Setup Dialog (Options item in the popup menu) . This defines how often the
graphic window display should be updated. Small values result in a fluid representation
of the signal response, but they place high demands on computer resources,
and with slower computers this might lead to performance problems.
High values, on the other hand, reduce computing demands but lead to a more
disturbed and delayed display of the signal response.
Statistics Window
Deactivate the statistics report in the Statistics window's popup menu to save on
computing power. Furthermore, the averaging time can be selected in the configuration
dialog of the Statistics block. Short time intervals place high demands
on computer resources and might result in severely oscillating lines in the window.
Very long averaging times make the display slower, but also less computing
intensive.
If you insert blocks in the real-time library, i.e. in CANoe's simulation setup, you
should ensure that they do not demand too much computing time, so that they do not
increase system reaction times. Furthermore, you may only access files in CAPL
programs if you observe special preventive.
On the other hand, it may be advisable at high bus loading to perform a data reduction
as early as in the real-time library to relieve loading in the evaluation branches of
CANoe.
It is not possible to predict an optimal configuration of the measurement and simulation
setups for all situations. Cyclic updating indeed saves computing time, but also
leads to poorer representation of the information. Under some circumstances it may
be advisable to completely disconnect analysis branches that are not needed in the
measurement setup (Insert Break item in the hot-spot's popup menu) or reduce the
volume of data at the input to the measurement setup using filter functions. Moreover,
you might also try to insert individual CAPL programs between the real-time
library and the evaluation branches and observe the behavior of the program during
another measurement run.
