CoverageMaster winAMS MBT Option

Back to back testing is essential for model based development, and can be streamlined with CoverageMaster winAMS

This is an option to efficiently perform Back to Back testing (hereinafter referred to as B to B testing), which is essential for model based development, using CoverageMaster winAMS. By using the microcontroller simulator available in CoverageMaster winAMS, the consistency between the model (MILS) and the target code (PIL simulation) can be verified.

Configuration of the CoverageMaster MBT option

In addition to the standard functions of CoverageMaster winAMS (CMW), the MBT option provides 7 functions to execute BtoB testing efficiently. By adding the optional BtoB testing function, an automatic BtoB testing environment can be constructed easily, which contributes to the reduction of testing work hours for BtoB testing.
  • Feature 1
    BtoB test execution, evaluation and report creation for models, software and target code in conjunction with CoverageMaster
    The CoverageMaster MBT option allows the execution of SILS and PILS using MILS execution operations and the CoverageMaster. The execution results can be compared using the functions of the MBT option and the consistency can be confirmed. It is possible to convert test data prepared using tools from other companies into the test data format of CoverageMaster.
  • Feature 2
    Full support for C0, C1 and MC/DC coverage at C code level as well as function/call coverage measurements in the integration phase
    With the functions of CoverageMaster it is possible to measure C0, C1 and MC/DC coverage at C code level and function/call coverage in the integration phase as required by the ISO 26262 standard for automotive functional safety.
Function

The CoverageMaster winAMS MBT option solves the challenges of Back to Back testing.

  • Function 01

    CoverageMaster features also available

    • PILS execution using a microcontroller simulator, coverage check of C0, C1, MC/DC and function calls at code level, test data generation from code and integration into a CI environment are possible. (*) Additional options are required for some functions. Please refer to the CoverageMaster winAMS Introduction Page

Main features

Test harness model generator You can isolate subsystems of the model to be verified and create test harness models for partial verification of individual subsystems.
I/O mapping function Based on the information of the test harness model and the variable information output from the CoverageMaster winAMS, a map list can be created by mapping the signals and variables to be compared. The overall tolerance can be set when creating the map list. Tolerance, fixed point setting and previous value setting for individual signals can be set by editing the map list.
Test data AD/DA conversion function From test CSV files created from models and source code, you can create CSV files for code testing and model testing. According to the fixed-point setting, the data of physical values created from the model are converted to digital values, and the data of digital values created from the code are converted to physical values.
MILS Execution Function The test harness model can be populated with data from the model test CSV file and a model execution results log can be created.
BtoB test matching function The code execution results log and the model execution results log can be compared to make a consistency judgment and create a comparison results data file. The error evaluation can be performed based on the tolerance of each signal and variable to be compared.
Integrated report generator Comparison result data files, model execution result logs and code execution result logs can be combined and output in XML and HTML formats.
