IAR Systems has boosted its support for Renesas microcontrollers (MCU) with two updates to its Embedded Workbench integrated development environment (IDE). The first, an updated version of the compiler and debugger toolchain for Renesas RL78, extends code quality control possibilities through enhanced static analysis as well as support for the latest RL78 devices. The enhanced static analysis functionality offers new checks within the add-on tool C-STAT, which performs advanced analysis on the source code level. The new version adds approximately 150 new checks to the existing wide range of checks, including 90 new MISRA C:2012 checks and two new packages of checks.
Several new options are also available, for example the possibility to enable or disable the false-positives elimination phase of the analysis as well as to exclude files from the analysis. C-STAT is fully integrated in the IAR Embedded Workbench IDE and aids developers in ensuring the code quality early in the development cycle. It detects defects, bugs and security vulnerabilities as defined by CERT C/C++ and the Common Weakness Enumeration (CWE), as well as helps keeping code compliant to the coding standards MISRA C:2004, MISRA C++:2008 and MISRA C:2012.
The second update is for the Renesas RX family, with identical features as described above. Version 2.90 of the complete C/C++ compiler and debugger toolchain offers extended static code analysis through C-STAT and the possibility to easily import Renesas Firmware Integration Technology (FIT) modules.
Renesas FIT is a technology that simplifies development of RX-based applications and improves portability between RX microcontrollers. It consists of a board support package (BSP), peripheral function modules, middleware modules and interface modules. The latest version of IAR Embedded Workbench for Renesas RX adds a tool for easy import of FIT modules. With this new integration, developers can use the imported FIT modules in IAR Embedded Workbench without having to make any adaptations to the imported code.
