The complete development toolchain IAR Embedded Workbench for Renesas R32C provides one toolbox in one view, giving you one uninterrupted workflow.

01

User-friendly IDE

Integrated development environment with project management tools and editor. Included is automatic checking of MISRA C rules (MISRA-C:2004), configuration files for all devices in R32C family, linker and library tools as well as example projects and code templates.

02

Powerful build tools

The IAR C/C++ Compiler is a highly optimizing C and C++ compiler for R32C. Included is also run-time libraries and a relocating R32C assembler.

03

Comprehensive debugger

The C-SPY Debugger with R32C simulator is included. It provides support for RTOS-aware debugging on hardware as well as Renesas E30 emulator, Renesas E8a emulator and Renesas E30A emulator. Included is also the C-SPY Debugger plugin SDK for 3rd party debuggers.

Latest releases

We are constantly updating and refining our tools with new features, new device support and extended capabilities.

Version 1.40

New text editor and source browser

A new text editor and source browser are introduced in this version. The new features include auto completion, parameter hint, code folding, block select, block indent, bracket matching, zoom and word/paragraph navigation. The new source browser adds features like Go to Declaration and Find All References to symbols.

Custom SFR window

It is now possible to define custom SFR's (special function registers) in C-SPY with selectable access size and type.

New licensing management system (LMS) introduced

The new LMS used with this release introduces new features like commuter licenses, automatic license activation and support for virtual servers. It is easier to administer and a new single CD concept enables all variants of IAR Embedded Workbench for a certain product to be included in one and the same installer.

Subversion

The version control integration has been extended with support for Subversion (SVN).

Updated device support

SFR header files, linker command files, and device description files have been added for the latest Renesas devices.

User guides and documentation

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

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.

Test validation

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.
