C, C++ Firmware System Test
C/C++ Firmware System Test is an embedded testing tool that can verify embedded software in the target of MCU (Micro Controller Unit) firmware software. Unlike traditional test tools that only test embedded software in the host development environment, this is the optimal test tool to perform embedded integration testing in MCU processor combining software and hardware. The MCU is used in an expanded role from a controller for simple signal control to the role of the brain of a small terminal. |

 Firmware System Testing Benefits
Test Program Execution: System (Whole Program)
UART protocol-based GUI Testing
Embedded Test Target Environment
-Software(code) + HW(MCU/ECU Processor) + Communication(UART)
Main Features of Firmware System Testing
Firmware System Test
-Code coverage verification/validation of Firmware SW
-Safety verification/validation of Target-based Embedded Firmware SW
Code Coverage Analysis and MBD based Path Verification
Code Coverage Analysis
-Unit Coverage: Statement, Branch, Path Coverage
-Integration Coverage: Function, Call Coverage
-MBD-based Requirement Coverage: Traceability(Forward), Consistency Coverage
-Code Coverage Analysis: On code, visual representation of tested coverage types and codes
MBD(Model-Based Design)-based Path Verification
-(program path verification) Comparison of paths of tested Statement/Branch and MC/DC
-(test-to-graph) Identification of path of bug based on MBD of expanded Control Flow Graph
-(test-to-code) Visualization of the coverage type (Statement(S), Branch(T, F)) of the tested code
Supported Compilers
C/C++ test supports all compiler families based on big-bang technique
-IAR, ARM, Borland, Cosmic, GNU, Green Hills, Intel, Keil, Green Hills, Intel, IAR, Microsoft, QNX, Wind River, etc.
Software Test Requirements Compliance
ISO 26262 (Automotive), DO-178 (Aerospace)
IEC 61508 (Industrial), IEC 62304 (Medical), EN 50128 & 50657 (Railway), etc.
Advantages of Automated Path Testing
Verification of safety and reliability of target-based embedded software
It helps to achieve high-quality code coverage quickly
It reduces software testing time by more than 100x compared to manual simulation testing
-Test Generation: Manual(Suppose one test case takes 10 minutes to complete the full testing) vs. Automation
It helps to fasten the time to market their software products
Main Practices
Embedded SW testing based on ISO 26262 (semiconductor)
-MCU firmware Test in target execution environment based on IAR Workbench in target
-11,116 LOC/272 Functions: 100% Statement Coverage by performing a total of 12 days
Embedded SW testing based on ISO 61508 (Subway)
-MCU firmware Test in target execution environment based on IAR Workbench in target
-1,946 LOC/111 Functions: 100% Statement Coverage by performing a total of 3 days
