How to Accurately Check Cycle Time for LIN Messages

How to Calculate Cycle Time for LIN Messages from ARXML or LDF Files

My Approach

1. From ARXML Files:

   • Extract the schedule tables for each cluster.

   • Identify the specific signal/message of interest within each schedule table for specific cluster.

   • Sum the delays for this specific signal.

2. From LDF Files:

   • Extract the schedule tables for specific cluster.

   • Identify the specific signal/message of interest.

   • Sum the delays for this specific signal across all schedule tables.

My Questions

1. Is this the correct approach to calculate the cycle time for a specific LIN message?

2. Are there any best practices or tools that can help automate this process?

Example

Scheadule_tables{    table1    {        signal1 : delay 10 ms,        signal2 : delay 20 ms    }    table2    {        signal1 :delay 10 ms    }    table3    {        signal2: delay 20 ms    } }

so in this scenario:

cyclicity time for signal 1 will be 20ms and cyclicity time for signal2 will be 40ms is this correct?
