MCAL Port Validation Tool*

This Tool validates the Microcontroller Peripheral Port Configurations for Texas Instrument Micro Controllers.

Features & Output

• Manual testing is not feasible.

• The Tool connects to Lauterbach and reads the Registers and dumps the register values.

• The register values are verified with the Data from the Micro Controller Manual.

• This Tool generates the report in ~2minutes.

• Stabilization of Voltage & Temperature signals for 6 projects.

• The tool verifies the Port Configuration by validating the Microcontroller registers

• Different settings like Pull down Enable, Interrupt, IO Type, Init Output Level are verified

• Validates AWR & TPR12 Controller based Radars.

• Challenges: Complexity of Microcontroller Architecture, Trace32 Integration, File Parsing using Regular Expressions

• The voltage stabilization script shall run for 5000 power cycles

Need

• ADAS Embedded systems use System On Chip and Micro Controllers by different Vendors like Texas Instruments and others.

• The Input and Output peripherals for the controllers are configured programmatically by using Third Party Tools like EB tresos.

• Port Configuration Settings like Pull down Enable, Interrupt, IO Type, Initial Output Level among others are configured on EB tresos and code is generated.

• Ports like CAN-H, CAN-L are configured.

• Once configured by the Developer, they are reviewed. But there is no Exhaustive Testing which confirms the configuration Settings.

• The MCAL Port Validation Tool

  • Developed in Python and uses CMM Scripting to access the Micro controller register settings during the Run time.

  • Verifies the Configuration Settings.

Goosebumps.

The Tool also identified the bugs with the Configuration Code Generation Tool (EB tresos).
