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 Support
Every tool we recommend for safety-critical projects is one we have used in our own compliance engagements. We supply and support these tools across India.

Safety & Compliance Insights
CEV Stage V Began in India on 1 January 2025
Trade coverage keeps putting CEV Stage V in October 2026. The gazette puts it on 1 January 2025, after one deferral and no band-by-band split. Here is the notification chain, what the October 2026 dates really govern, and what the limits mean on the bench.
AI, Rust and the New Functional Safety Standards
AI has entered both the development flow and the shipped product, Rust is taking new safety-critical code that would once have been C, and the guidance layer is moving to cover both. A guide to five Perforce resources on that shift, from the GSAS engineering team in India.
ISO 19014 for ISO 26262 Engineers: MPL Is Not ASIL
India's functional safety talent pool grew up automotive. Earth-moving machinery answers to a different series with a different family tree, and reading one through the lens of the other produces confident, expensive errors.
Automotive Ethernet Conformance: TC8 and Testing Above It
Summarising TC8 as a layer 1 to layer 4 suite is wrong in both directions. The public OPEN Alliance ECU test documents run from transmitter distortion up to a SOME/IP chapter with its own standardised test stub, and they contain exactly one time synchronisation test case. This is what those documents enumerate, chapter by chapter, what genuinely lives above their boundary, why a passing ECU can still fail against a partner node, and how much pre-compliance work a Tier-1 in India can honestly do in-house before a test house visit. Written by the GSAS Micro Systems engineering team in India.
Fault Injection in HIL: Open Load, Shorts, Malformed Frames
Fault injection material splits in two. Switching-hardware pages describe relay matrices and open-load wiring; software-testing posts describe malformed input. A vehicle network fails across both at once, because an intermittent short changes link quality and the stack above then behaves badly. This article puts electrical and protocol faults into one campaign, writes the observable and the expected reaction down per fault, and treats the fault insertion hardware itself as a signal-integrity risk you have to characterise before you trust a result. Written by the GSAS Micro Systems engineering team in India.
SecOC vs MACsec vs TLS: Automotive Security Layers
SecOC, MACsec and TLS get compared as if a programme picks one. They are three different scopes, and most vehicles carry more than one. This article separates them in a single table by scope, unit protected, key source and what a capture still shows, then covers the two things almost nobody writes down: what each layer does to your ability to debug, and why an ECU can reject a message whose authenticator is perfectly valid after a reset. Protocol claims trace to the public AUTOSAR SecOC protocol specification, IEEE 802.1, the Wireshark dissector sources and Linux networking documentation.
