IAR Embedded Workbench for - Library Source 8.20

IAR Embedded Workbench – Library Source by IAR Systems

IAR Embedded Workbench – Library Source is an add-on that provides the full source code for the C/C++ runtime libraries supplied with IAR Embedded Workbench for your chosen architecture. It gives embedded developers the visibility and control needed to inspect, debug, and tailor the runtime libraries to meet specific hardware, performance, footprint, or compliance requirements.

Key capabilities:

• Access to source for core runtime components, including standard C/C++ libraries, low-level I/O layers, math routines, startup/system initialization templates, and typical variants (for example, small/fast, thread-safe, and floating-point options).
• Step-into debugging of library code to accelerate root-cause analysis and improve understanding of runtime behavior.
• Customization of I/O retargeting (such as printf/scanf), memory models, heap/stack handling, and locale/wide-character support to optimize size and determinism.
• Support for rigorous code reviews, static analysis, and documentation needs common in safety- and security-critical development.

Who it’s for:

• Teams building resource-constrained or safety-critical embedded systems that require fine-grained control, traceability, or certification evidence.
• Developers who need to modify or audit runtime behavior, integrate with an RTOS, or minimize code size and execution time.

Notes:

• Requires a licensed copy of IAR Embedded Workbench for the relevant target architecture.
• Availability and included components may vary by architecture and version.
