Hitex upgrades TESSY tool to support Melexis' MCUs

Hitex Development Tools has revealed that version 3.0.22 of their TESSY tool for automated unit/module/integration testing of embedded software has added support for Melexis' microcontrollers.

TESSY can use the development environment Melexis' Mlx16, allowing microcontrollers developed in this environment to be supported by TESSY. Microcontrollers that can be used include the Mlx-16, Mlx16-8, Mlx16-x8 and Mlx-FX. Such microcontrollers handle for instance the LIN bus protocol or control brushless electric motors.

Automated tests can be executed either in a simulation of the microcontroller on the Windows host or directly on the actual hardware of the microcontroller. TESSY uses the gcc-based compiler from Melexis to compile and link the test application that tool automatically generates. The tool loads the test application automatically in the simulator/emulator of Melexis and then executes the tests.

TESSY provides all its usual functionality also for the microcontrollers of Melexis. This comprises for instance measurement of the code coverage, software integration testing, automatic test report generation or the traceability of requirements to test cases. Furthermore, TESSY is able to create a special test application with built-in test data, which the user then can load via the interactive debugger Mlx16 from Melexis in the microcontroller in question, either on the actual hardware or in a software simulation of the microcontroller. This allows easy investigation of the reason of a failed test case.

For the test of safety-critical applications it is advantageous that TESSY is already qualified to be used in safety-related software development according to IEC 61508 and ISO 26262.

TESSY is available from Hitex Development Tools GmbH.
