Slide: 7

Runtime Measurement (RTM)

Runtime measurement of:

User defined code sections (application and BSW)

Response times of asynchronous activities

Interrupt locking times

SWC runnables

…

CPU load measurement:

Code section specific

Overall CPU load

Slide: 8

Runtime Measurement (RTM)

Measurement Point Configuration

User Measurement points are configured in DaVinci Configurator

Selected BSW modules provide predefined measurement points

E.g. Driver interrupt routines, main- and init Functions

Integration of user measurement points

Add start and stop API calls for each measurement to your code

Slide: 11

Runtime Measurement (RTM)

Measurement Results

Min/Max/Average runtime

Number of measurements taken

CPU load (in %) of measured code section

Notification function reporting unexpected high runtime

Helps detecting problematic code sections

Overall CPU Load (Live Mode)

Outlook

Measurement of net runtime (R9 – Q1 2014)

Removal of runtime inflicted external sources e.g. interrupts or callouts

Debugging (DBG)

BSW and RTE Variable Access

Determine the status of BSW modules in real-time

Access to S/R communication data of SWCs

Available for selected MICROSAR BSW module variables

Slide: 15

Debugging (DBG)

Read Function Return Values (available with R9 – Q1 2014)

DBG can trigger any API and relay the result to CANoe via XCP

Use-Case example: Determine OS stack usage

Call frequency and activation controlled via CANoe frontend

Slide: 16

Debugging (DBG)

Easy to use:

No BSW configuration or integration required

DBG generates A2L file describing available variables

Variable illustration with XCP tool (CANoe.AMD or CANape)

Multiple ways of processing and displaying the data

Example: CANoe state tracker display

Usage of XCP

MICROSAR DLT and DBG use XCP

XCP is a standardized protocol widely used

Existing XCP tools and workflow can be used

XCP was designed to visualize ECU internal data

By using XCP MICROSAR AMD remain lightweight modules

XCP Solution is favored over the AUTOSAR solution by several OEMs
