CMSIS-Core Validation

This folder contains a test suite that validates CMSIS-Core implementations. It uses Fixed Virtual Platforms to run tests to verify correct operation of the CMSIS-Core functionality on various Arm Cortex based processors.

Folder structure

    📂 CoreValidation
    ┣ 📂 Include        Include files for test cases etc.
    ┣ 📂 Layer          Layers for creating the projects.

Prerequisites

The following tools are required to build and run the CoreValidation tests:

CMSIS-Toolbox 1.3.0 or higher
CMake
Ninja build
Arm Compiler 6
GNU Compiler
IAR Compiler
Python 3.8 or higher
Arm Virtual Hardware Models

The executables need to be present on the PATH.

Install the Python packages required by build.py:

CMSIS_5/CMSIS/CoreValidation/Project $ pip install -r requirements.txt

Build and run

To build and run the CoreValidation tests for one or more configurations use the following command line. Select the <compiler>, <device>, and optimize level to build and run for.

CMSIS_5/CMSIS/CoreValidation/Project $ ./build.py -c <compiler> -d <device> -o <optimize> [build] [run]

For example, build and run the tests using GCC for Cortex-M3 with low optimization, execute:

CMSIS_5/CMSIS/CoreValidation/Project $ ./build.py -c GCC -d CM3 -o low build run
[GCC][Cortex-M3][low](build:csolution) csolution convert -s Validation.csolution.yml -c Validation.GCC_low+CM3
[GCC][Cortex-M3][low](build:csolution) csolution succeeded with exit code 0
[GCC][Cortex-M3][low](build:cbuild) cbuild Validation.GCC_low+CM3/Validation.GCC_low+CM3.cprj
[GCC][Cortex-M3][low](build:cbuild) cbuild succeeded with exit code 0
[GCC][Cortex-M3][low](run:model_exec) VHT_MPS2_Cortex-M3 -q --simlimit 100 -f ../Layer/Target/CM3/model_config.txt -a Validation.GCC_low+CM3/Validation.GCC_low+CM3_outdir/Validation.GCC_low+CM3.elf
[GCC][Cortex-M3][low](run:model_exec) VHT_MPS2_Cortex-M3 succeeded with exit code 0
