What its author says it does

Copied from the file, not written here

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.

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: simulation_basics.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
Key Tools: gdb, valgrind, gprof, pcap.

3. Automated Testing (CI/CD)

The foundation of modern firmware development.

Reference: See the testing-debugging skill (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 debug

Automation Tools

native_log_scan.py: Scan native simulation logs for common crash/failure signatures.

Examples & Templates

native_sim_ci_checklist.md: Starter checklist for CI simulation coverage.

Validation Checklist

west build -b native_sim succeeds 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).
