03
Leading compiler technology
The IAR C/C++ Compiler is built by our compiler experts and supports C and C++. It offers advanced global and target-specific optimizations, and supports a wide range of industry-standard debug and image formats, compatible with most popular debuggers and emulators, including ELF/DWARF where applicable. Coupled with the complete linker and assembler, it enables powerful building of embedded applications.
04
Comprehensive debugger
The C-SPY Debugger provides an Arm instruction simulator and extensive support for debugging probes and target systems. It includes RTOS plugins and wide support for communication stacks and middleware, as well as a C-like macro system. In addition, it offers multicore debugging with support for symmetric multicore processing (SMP) and asymmetric multicore processing (AMP).
05
On-demand training included
When you buy a license of IAR Embedded Workbench for Arm, you get access to free training courses through our IAR Academy on Demand offering.
06
Integrated code analysis add-ons
Through the integrated static analysis add-on C-STAT and the runtime analysis add-on C-RUN, the toolchain helps you to ensure code quality throughout the development and testing process.
