Code quality ensured for developers working with automotive MCUs

By using C-STAT, developers can ensure the quality of their code and find potential issues by doing an analysis on the source code level. Such issues include memory leaks, dead code, arithmetic errors and array and string overruns that can cause safety and security issues and affect the performance and quality of a product.

C-STAT checks compliance with rules as defined by the coding standards MISRA C:2004, MISRA C++:2008 and MISRA C:2012, as well as hundreds of rules based on for example CWE (the Common Weakness Enumeration) and the CERT C/C++ Secure Coding Standards. It is a powerful static analysis tool that is completely integrated in IAR Embedded Workbench, with the settings and results provided directly in the IDE.

Renesas' RH850 Family offers high performance balanced with low-power consumption over a wide and scalable range of products supporting high reliability requirements. IAR Embedded Workbench for RH850 is a complete development toolchain including the highly optimising IAR C/C++ Compiler and the comprehensive C-SPY Debugger incorporated in a user-friendly integrated development environment.

In addition to C-STAT, the latest version of IAR Embedded Workbench for RH850 adds new debugging functionality including the possibility to connect an E1 or E20 emulator to a running system to inspect it without interrupting programme execution. For the E1 and E20 emulators, the debugger now also supports using either 1-pin or 4-pin LPD (Low Pin Debug) communication with adjustable speed. Also introduced is a new option to select the precision used by the compiler for representing the floating-point types double and long double. The compiler can use either 32-bit or 64-bit precision. In addition, support for the latest Renesas RH850 devices has been added.

Launched in February 2015, C-STAT is continuously being rolled out as an add-on tool in the IAR Embedded Workbench product family.
