Functional Safety
Functional Safety & Compliance
End-to-end safety lifecycle engineering, hazard analysis, FMEA, safety case development, tool qualification, and assessor-ready evidence packages. From automotive ASIL-D to aerospace DAL A, delivered by India's embedded safety specialists.
Safety Lifecycle
V-Model Safety Engineering
Every functional safety engagement follows a structured lifecycle from hazard analysis through validated safety case. We cover the full V-model, not just the comfortable middle.
Hazard Analysis & Risk Assessment
Systematic identification of hazards, determination of safety integrity levels, and definition of safety goals. HARA, FTA, FMEA, and FMEDA methodologies applied across automotive, industrial, aerospace, and medical domains.
Safety Concept & Architecture
Technical safety concept development, safety-relevant architecture decomposition, hardware-software interface specification, and freedom from interference analysis for multi-core and mixed-criticality systems.
Implementation & Verification
Safety-compliant code development with MISRA C/C++ adherence, unit testing with MC/DC coverage, static analysis, and requirements traceability from safety goals through code.
Validation & Safety Case
End-to-end safety case development, compiling all evidence, verification reports, and compliance arguments into assessor-ready documentation packages.
Tool Qualification
Tool Confidence Level assessment and tool qualification per ISO 26262 Part 8, IEC 61508 Part 3, or DO-330. We produce the Tool Qualification Plan, Tool Qualification Report, and manage the assessor dialogue.

Tool Qualification
TUV SUD Process Expertise
Tool qualification is where most safety projects stall. GSAS has deep experience in the TUV SUD assessment process, we know what assessors expect, what evidence satisfies each objective, and how to structure the Tool Qualification Plan and Report to pass review on first submission.
We have qualified development tools (compilers, IDEs), verification tools (test frameworks, static analyzers), and production tools (flash programmers) across ISO 26262, IEC 61508, and DO-330.
Toolchain
Safety-Qualified Tools We Distribute
Every tool we recommend for safety-critical projects is one we have used in our own compliance engagements. We distribute and support these tools across India.

Safety & Compliance Insights
Shift-Left for Safety-Critical Code: Perforce QAC Static Analysis + Razorcat TESSY Dynamic Testing for MISRA, IEC 62304 and FDA Compliance in India
Run Perforce QAC static analysis first to enforce MISRA and clean the code, then Razorcat TESSY for dynamic unit testing and MC/DC coverage. Together they form a complete shift-left toolchain for IEC 62304 medical-device and FDA-regulated software, both from one authorized engineering partner in India, GSAS Micro Systems.
Flex and Rigid-Flex Design Optimization: DFM, Creepage, and Signal Integrity for Indian PCB Teams
Smart and affordable DFM tools for Indian SMB teams designing flex and rigid-flex PCBs. How Siemens HyperLynx, Valor NPI, and automated creepage checking reduce NPI time and prevent expensive re-spins.
SafeTpal vs In-House Self-Test for AURIX: Choosing the Right Safety Test Strategy
Infineon's SafeTpal library provides pre-certified safety self-tests for AURIX TC3xx/TC4xx. But when does it make sense to build custom routines instead? We compare both approaches through the lens of ISO 26262 compliance.
ISO 26262 Part 6 Unit Testing Requirements: A Practical Checklist Mapped to TESSY Capabilities
ISO 26262 Part 6 governs software unit design and implementation.
MC/DC Coverage Explained: What It Is, Why You Need It, and How TESSY Achieves 100%
A practical guide to Modified Condition/Decision Coverage (MC/DC), the structural coverage metric required by ISO 26262 ASIL D and DO-178C DAL A. Explains what MC/DC measures, why it matters, and how Razorcat TESSY helps engineers achieve 100%.
