Native Sim
Host-based simulation using the Zephyr native_sim board. Covers building for Linux/macOS/Windows, automated testing, host-side debugging (GDB, Valgrind), and host-target integration. Trigger when developing application logic without hardware or setting up CI/CD tests.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Zephyr Native Simulation
Develop, test, and debug Zephyr applications with the speed and convenience of your host machine.
Core Workflows
1. Simulation Basics
Understand when to use native_sim vs. QEMU and how to map host resources.
- Reference: [simulationbasics.md](references/simulationbasics.md)
- Key Tools:
west build -b native_sim.
2. Host-Side Debugging
Use professional host tools to find the most elusive bugs.
- Reference: [debugging.md](references/debugging.md)
- Key Tools:
gdb,valgrind,gprof,pcap.
3. Automated Testing (CI/CD)
The foundation of modern firmware development.
- Reference: See the
testing-debuggingskill (Phase 3) for comprehensive testing workflows. - Key Tools:
twister -p native_sim.
Quick Start
# Build for host
west build -b native_sim samples/hello_world
# Run the app
./build/zephyr/zephyr.exe
# Debug with GDB
west debugAutomation Tools
- [nativelogscan.py](scripts/nativelogscan.py): Scan native simulation logs for common crash/failure signatures.

Validation Checklist
- [ ]
west build -b native_simsucceeds for at least one sample and one app target. - [ ] Built binary runs on host and emits expected startup logs.
- [ ] Host debugger (GDB/Valgrind) can attach and surface expected symbols.
- [ ] Simulation test path is integrated into CI (for example Twister native_sim run).
