This block provides the statistics for all streams terminating at this Node. This block can be connected either to the Node block or the Traffic Generator.
This block provides 2 types of statistics- two files that contain the trace and statistics for all the streams, and 3 possible plots- latency of all streams, histogram of all the streams and a single stream plot.
Both text files are written into the directory containing the model. The first text file is named; TTE_Example_Stream_Plot.Stats.Node_5_Stream_Latency.txt and the second is Information_Warning.txt. The first file contains the minimum, maximum, mean and standard deviation of the latency, and the throughput for all the streams twerminating at this Node.
The all stream latency is displayed by default. The legend on right is of the format- Start Node, End Node and Stream or Ethernet number. The Ethernet number is the order in the Traffic Table. The stream number is the ID. The histogram plot shows the histogram for each stream. The single stream latency plot can be enabled by setting Enable_Second_Plot parameter to true. The second plot will plot a single stream that is set in Second_Plot_Contains parameter.
TTE_Stats
block requires a number of mandatory data structure fields including
Task_Source, Task_Destination, Task_Hop, Task_Trace, Task_Size, Type,
Network_Message, Network_Message_Type and Task_Layer. Hence, it is
recommended to use TTE_Traffic block to generate transactions for
configured TTEthernet network. Other blocks that are required along
with TT_Stats block are as follows; TTE_Bridge, TTE_Config, TTE_Node
1. TTE Example System with three Sources and One Destination with Single Bridge
2. TTE Example System with Multi-Bridge
3. TTE Example System with two Redundant Connections

Enable_Write_to_File |
Enabling this writes the statistics to the file |
|
|
Node_Name |
Name of the Node that this block is connected too. |
String |
"Node_" + Number |
Enable_Histogram |
enables the histogram plot for all the stream terminating at this Node. |
|
|
Enable_Second_Plot |
Enabling this adds another plot for a single latency |
|
|
Second_Plot_Contains |
Format for TTE stream is {"N1","Stream_1"} and for Ethernet is {"N1","Ether_1"}. The N1 is the Source Node with the Node_ abbreviated to N. The Stream or Ether _1 is the number of the Traffic Table order. |
String Array |
Format for TTE stream is {"N1","Stream_1"} and for Ethernet is {"N1","Ether_1"} |
