Search tips

apple banana
Find rows that contain at least one of the two words.

+apple +juice
Find rows that contain both words.

+apple macintosh
Find rows that contain the word 'apple', but rank rows higher if they also contain 'macintosh'.

+apple -macintosh
Find rows that contain the word 'apple' but not 'macintosh'.

+apple ~macintosh
Find rows that contain the word 'apple', but if the row also contains the word 'macintosh', rate it lower than if row does not. This is "softer" than a search for '+apple -macintosh', for which the presence of 'macintosh' causes the row not to be returned at all.

+apple +(>turnover >strudel)
Find rows that contain the words 'apple' and 'turnover', or 'apple' and 'strudel' (in any order), but rank 'apple turnover' higher than 'apple strudel'.

apple*
Find rows that contain words such as 'apple', 'apples', 'applesauce', or 'applet'.

Optimization of CANoe/CANalyzer Performance

Last updated: 2018-08-14
Question:
How to optimize CANoe/CANalyzer performance?
Answer:
If there is a performance issue with CANoe/CANalyzer, the following symptoms can occur:
  • CANoe/CANalyzer is in overload mode
  • Messages can be lost
  • rx queue overrun
  • CANoe/CANalyzer windows will be deactivated


If one or more of the above mentioned symptoms occur, please follow this instruction:

1. Optimize performance: File | Help | Optimization. See messages in write window.




In older CANoe/CANalyzer versions see Configuration | Options | Measurement | Performance | Optimize Performance



2. Switch off data history File| Options | Measurement | Data history short.



In older CANoe/CANalyzer versions see Configuration | Options | Measurement | Data history: None with short data history

3. Deactivate unused windows in View | Measurement Setup:

4. If a bus system is simulated, but the data is not needed for the analysis, a filter can be used. All Measurement Setup features are not available any more. See: Configuration | Options | Measurement | Performance | Throughput

5. When working with many different channels, the queue size between RT and Display Part is often too small. Therefore, the EventQueueSize and EventSorterLimit in CAN.ini have to be enlarged.

The CAN.ini could be found in Start | Program Files | Vector CANoe or Vector CANalyzer | CAN.ini

Hint:

A PC with high performance is needed!

E. g. PC mit Xenon processor, 24x CAN, 26x LIN, 2x FlexRay

Enlarge EventQueueSize from 55000 to 200000
Enlarge EventSorterLimit from 49000 to 100000
