IAR Embedded Workbench for Renesas V850 provides integrated static code analysis through the add-C-STAT, ensuring code quality as well as proving alignment with standards such as MISRA C:2012.
On-demand training included
When you buy a license of IAR Embedded Workbench for Renesas V850, you get access to free training courses through our IAR Academy on Demand offering.
We are constantly updating and refining our tools with new features, new device support and extended capabilities.
Updated IDE look and feel
The IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials.
Enhanced Registers and Symbols windows in C-SPY
The C-SPY Symbols and Registers windows have been re-designed with new features. The Symbols window now has a filtering function and a new column displaying to which program module a certain symbol belongs. Some of the new features in the Registers window are drag-and-drop support from source code windows, detailed register tool-tip information, and improved handling of user-defined registers groups.
Improved C-STAT Static analysis
- New checks have been added including about 20 new checks in the MISRA C 2004 package.
- Improved analysis engine which increases the analysis precision.
- The time-consuming false-positive analysis is now disabled by default but can be enabled by an option in the IAR Embedded Workbench IDE or on the command line.
- A new option in the IAR Embedded Workbench IDE makes it possible to limit the number of messages generated per check and per file.
- C-STAT message suppression can now be controlled by directives placed in comments in the source files.
- A new option --deterministic has been added to ensure a deterministic amount of messages when running icstat with multiple threads, so that the amount of messages stays approximately the same from one analysis run to another. This option puts a limit on the option --parallel.
Updated user documentation
The IDE Project Management and Building Guide has been updated to reflect the product changes.Read complete release notes
The add-on product C-STAT for static analysis is now supported. C-STAT features innovative static analysis that can detect defects, bugs, and security vulnerabilities as defined by CERT and the Common Weakness Enumeration, as well as help keeping code compliant to coding standards like MISRA C:2012/2004 or MISRA C++:2008.
IAR Embedded Workbench can now build projects using multiple parallel processes. This can improve build performance significantly on multi-core or multiple processor computers. To enable parallel build, select Tools>Options>Project>Enable parallel build.
Custom argument variables
Custom argument variables can be used in IAR Embedded Workbench whenever there is a need for a macro-like expansion that depends on the current context. This could for example be in arguments to an external build tool.
Saving C-SPY Watch window content
In the C-SPY Watch window family, you can now choose Save All to File from the context menu to save the contents of the current window to a text file.
Updated device support
SFR header files, linker configuration files, and device description files have been added for the latest Renesas devices.
Updated user documentation
The IDE Project Management and Building Guide, and the C-SPY Debugging Guide have been updated to reflect the product changes.Read full release notes

Languages and standards
The IAR C/C++ compilers offer different dialects of the C and C++ programming languages, as well as different extensions specific for embedded programming (please note that not all language standards are supported for all target implementations). The compiler can be instructed to disable extensions for strict conformance to the standards.
A wide range of industry-standard debug and image formats compatible with most popular debuggers and emulators are supported. This includes ELF/DWARF where applicable.
ISO/ANSI C/C++ Compliance
The IAR C/C++ compilers adhere to a freestanding implementation of the following C programming language standards:
- INCITS/ISO/IEC 9899:2018, known as C18 (Latest version only).
- The compiler supports all C++17 features. The C++ library supports C++14 with no C++17 additions. (Latest version only).
- ISO/IEC 14882:2015, known as C++14
- INCITS/ISO/IEC 9899:2012, known as C11
- ANSI X3.159-1989, known as C89
The ISO/ANSI C/C++ Compliance level varies between the different compilers. For complete information, please refer to the IAR C/C++ Compiler user documentation in your chosen product.
IEEE 754 standard
IAR Embedded Workbench supports the IEEE 754 standard for floating-point arithmetic.
MISRA C is a software development standard for the C programming language developed by MISRA, The Motor Industry Software Reliability Association. Its aims are to facilitate code safety, portability and reliability in the context of embedded systems, specifically those systems programmed in ISO C.
The first edition of the MISRA C standard, "Guidelines for the use of the C language in vehicle based software", was produced in 1998. In 2004, a second edition was produced with many substantial changes to the guidelines, including a complete renumbering of the rules. Additionally MISRA C:2012 with extended support and MISRA C++:2008 for identifying unsafe code constructs in the C++ standard have also been added to the standards.
IAR Embedded Workbench features an add-on product C-STAT so you can check compliance with rules as defined by MISRA C:2004, MISRA C++:2008 and MISRA C:2012.
We use the following commercial test suites to test conformance of our tools to the standards:
- Plum Hall Validation test suite for ISO/IEC C conformance
- Perennial EC++ Validation Suite for C++ conformance
- Dinkum C++ Proofer to test how our libraries conform to the C and C++ standard as well as test our STL implementation against the C++ standard.
In addition to the commercial suites, we use several in-house test suites for testing new features, regression testing, corrected errors, etc.
