Shift-Left Engineering Intelligence • Zero Verification Surprises

Know the Downstream Safety Blast Radius Before Git Commit

Hardware, embedded firmware, and biomedical engineers build best when they aren't trapped in clunky eQMS portals. PMX OS embeds safety hazards, standards limits, and trace links directly into your pull requests, CAD checks, and CI/CD pipelines.

The Engineering Trap

The Late-Stage Verification Shock

An embedded developer tweaks a sensor sampling loop in C++ to extend battery life by 12%. The code passes all unit tests and merges cleanly into main.

Six months later, during formal Design Verification in an accredited test house, the unit fails biological safety testing: the higher instantaneous burst current caused a localized thermal peak that violated IEC 60601-1-11.

Result: $120,000 in scraped prototypes, an emergency PCB redesign, and a 6-month delay in filing FDA 510(k).

Modern Developer Toolchain

Compliance as Code, Not Bureaucracy

Integrate PMX OS directly into your daily development environment via CLI, GitHub Actions, and CAD plugins.

CLI & Git Pre-Commit Hooks

Run pmx verify in your local terminal. The graph evaluates your staged diff against system requirements and warns you if your commit breaks an approved risk mitigation.

CAD BOM Synchronization

Export Altium schematics or SolidWorks assemblies. PMX OS extracts manufacturer part numbers, verifies RoHS/REACH compliance, and checks thermal dissipation boundaries automatically.

Automated Test Bench Ingestion

Feed automated LabVIEW, Python PyTest, or oscilloscope CSV captures straight into PMX OS. Evidence nodes are cryptographically signed and attached to verification protocols (V-Nodes).

Engineering Resolves Change CHG-1024 with Zero Scrap

Walk through the exact developer flow used to swap sensor S-18 with S-22 without breaking device design controls.

Step 1 • Sandbox Experimentation

Evaluating the Thermal Profile

The hardware team opened the PMX Change Simulator to test swapping discontinued transducer S-18 with substitute S-22.

The simulator immediately presented the full blast radius: assembly ASM-9022, thermal requirement REQ-0184, and hazard RSK-0044. Instead of making physical tooling commitments blindly, engineering knew exactly which bench test had to be verified.

Step 2 • Test Bench Upload & Pass

Closing the Evidence Gap (V-0183)

The engineer hooked up prototype board SN-0442 inside a 40°C environmental chamber and ran automated data collection script test_thermal_dissipation.py.

Peak Contact Temp: 40.18°C ≤ 41.0°C Threshold → STATUS: PASS

The test log was signed and pushed to PMX OS. The status indicator on CardioSense Pro v3.8.2 changed from "Attention" to "Verified".
