LDRA, a provider of automated software verification, source code analysis, and test tools, has integrated the LDRA tool suite with the IAR Embedded Workbench for the PIC18, AVR, AVR32 and MSP430 microcontrollers.
IAR Embedded Workbench provides full ANSI C compliance, support for embedded C++ as well as host-controlled I/O facilities not typically available for these microcontrollers. LDRA has been able to leverage these capabilities to add static analysis, code coverage to Modified Condition/Decision Coverage (MC/DC), and requirement traceability on these resource-constrained footprints.
The LDRA tool suite fully hooks into these PIC, Atmel and TI tool chains, allowing for compilation, linking, programming, and execution in these environments. LDRA Testbed can read IAR project files and use these files to speed static analysis efforts by reading include paths, macros and other settings. In addition, LDRA Testbed and LDRA TBrun use the project files to compile, control IAR’s simulation and device-programming environments, execute on target, and extract the results. With this, developers get a head start on performing system and unit tests using the already available IAR infrastructure.
The LDRA tool suite integration enables these microcontrollers to be used in DO-178B and similar medical and industrial certification environments. With medical standards now pushing medical device vendors to produce test output results that conform to MC/DC certification criteria, these capabilities are increasingly important. Since these capabilities are available in hosted as well as microprocessor-based devices, enterprises can standardize on LDRA and IAR as a common set of tools that developers can use to support a variety of devices and target environments.
