Embedded systems test platform for streamlined ISO 26262 compliance
Mx-Suite, Danlaw's embedded systems test platform, offers a back-to-back testing solution between MathWorks Simulink models and Lauterbach TRACE32 emulators. By using the same test tool and the same test cases in both environments, equivalence between the model and its generated C code is demonstrated, eliminating the effort of creating a second suite of tests for the target environment.
With the platform, the effort in achieving ISO 26262 compliance is noticeably reduced—by comprehensively testing the generated code, the need to qualify the code generator for ISO 26262 is eliminated. Furthermore, according to the ISO 26262-6 Road Vehicle – Functional Safety specification, "the test environment for the software unit testing shall correspond as closely as possible to the target environment." Through back-to-back testing, the effort devoted to testing on the target is virtually eliminated. ISO 26262-6 recommends performing code coverage measurements. Mx-Suite leverages Danlaw's RapiCover code coverage tool to transparently automate the capture of MC/DC code coverage statistics, while tests are executing on the TRACE32 emulation target platform.
"When qualifying a software development tool chain for ISO 26262, every component of the tool chain has to be addressed. By using Mx-Suite for MiL, SiL, HiL, and now PiL, the qualification effort is drastically reduced. In addition, by reusing test cases between MiL and PiL, the need to qualify the code generator can be eliminated," said Michael McCormack, Danlaw's Director of Development.
"TRACE32 offers comprehensive support for automotive processors coupled with powerful debug and trace features that allow a seamless transition to on-target testing. Testing can start on development platforms or make use of virtual targets before the first hardware prototypes are available. By combining Mx-Suite with TRACE32, our customers can reap the benefits of early on-target testing: detecting errors early and reducing the time to market," said Stephan Lauterbach, General Manager of Lauterbach.
