Automotive & Mobility
Accelerate Software-Defined Vehicle Development.
End-to-end toolchains for ADAS, powertrain, body electronics, and connected vehicle platforms, with functional safety and cybersecurity built in.
The automotive industry is undergoing a fundamental transformation driven by electrification, connectivity, and autonomous driving. Software now defines vehicle capability, with modern cars running over 100 million lines of code across dozens of Electronic Control Units. GSAS provides the complete embedded development toolchain that automotive engineering teams need to build, test, and certify software-defined vehicle platforms.
Our curated portfolio addresses every stage of the automotive V-model, from requirements and architecture through unit testing, integration, and production deployment. Klocwork and Helix QAC deliver MISRA and AUTOSAR compliance analysis for ISO 26262, while TESSY by Razorcat provides automated unit testing with MC/DC coverage measurement qualified for ASIL D. J-Link PRO and PicoScope enable deep hardware-software integration debugging across CAN, LIN, and FlexRay networks, and our automotive Ethernet capture and validation capability extends the same bench discipline to 100BASE-T1, SOME/IP, and DoIP.
With UNECE R155/R156 and the EU Cyber Resilience Act reshaping the regulatory landscape, cybersecurity is no longer optional. GSAS partners with Perforce (Klocwork, Helix QAC) to deliver static analysis, vulnerability management, and AUTOSAR-compliant development environments that meet both safety and security mandates from day one.

Latest Thinking: Automotive & Mobility
100BASE-T1 Link Won't Come Up: A Vendor-Neutral Checklist
A 100BASE-T1 link that will not come up is almost never a mystery, but the answers on the web are written per silicon vendor and do not transfer. This is the ordered bring-up checklist that holds regardless of which PHY, switch or SoC you have: physical layer first, then the PHY over MDIO, then the master and slave pairing, then the causes of a link that comes up and drops. The standards and tooling claims trace to IEEE 802.3 task force records, the Linux ethtool and kernel documentation or published test material. Written by the GSAS Micro Systems engineering team in India.
100BASE-T1 Media Converters: How to Choose One
Search for a 100BASE-T1 media converter and you get SKU pages that document their own DIP switches, plus a pile of copper-to-fibre converters that have nothing to do with single-pair automotive Ethernet. This is the selection guide neither publishes: what the box does at the PHY layer, when a converter is the wrong box, and the nine criteria that decide fitness, each written as a question to put to the supplier rather than a specification we invented. Standards claims trace to IEEE 802.3 task force records and the public OPEN Alliance specifications. Written by the GSAS Micro Systems engineering team in India.
10BASE-T1S and PLCA: Multidrop Ethernet Explained
10BASE-T1S is the one member of the T1 single-pair Ethernet family that keeps a shared medium, and PLCA is the reconciliation sublayer that stops the nodes on it from colliding. This article covers what IEEE 802.3cg standardises, how the beacon and transmit opportunities schedule a cycle, the node count and segment length figures the OPEN Alliance interoperability test suite works to, and the failure modes that put a segment quietly back into contention while every link still looks up. Written by the GSAS Micro Systems engineering team in India for teams bringing up multidrop segments on the bench.
ADAS Sensor Data Logging: Bandwidth Budgets That Add Up
Every page that tells you an ADAS test vehicle produces terabytes a day states the headline and skips the arithmetic, so you cannot redo it for your own sensor set. This article publishes the arithmetic instead: one formula, every table row derived on the page, a worked eight-hour drive that chains those rows into a sustained write rate, a media count and an offload window, and the five places bandwidth budgets go wrong. Written by the GSAS Micro Systems engineering team in India.
Automotive Data Loggers: Capture Without Loss
Search for an automotive data logger and the results split into cheap OBD dongles at one end and enterprise ADAS recorders at the other, with nothing in between explaining the engineering that decides whether you lose frames. This is the loss budget end to end: mirror oversubscription upstream of the logger, encapsulation overhead on the capture path, sustained write rate against burst rate, rotation stalls, and storage arithmetic worked in full so you can redo it with your own numbers instead of trusting ours. Written by the GSAS Micro Systems engineering team in India.
Automotive Ethernet Connectors: H-MTD, MATEnet, MQS
An ECU arrives on the bench with a connector nobody has a mate for, and the day is gone. Search the family names and you get connector product pages that describe their own part and stop there. This article puts the families side by side in one table using only what their public pages state, then makes the point those pages leave out: the IEEE link segment definition, not the connector, is what sets reach and loss limits, and shielding is a channel decision rather than a preference. Written by the GSAS Micro Systems engineering team in India.
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.
How to Choose an Automotive Ethernet Switch for the Lab
Search for an automotive Ethernet switch and you get silicon selection tables written for the engineer choosing a die for a zonal controller. The person searching from a validation lab wants a boxed switch that reproduces a vehicle network on a bench, and finds nothing addressed to them. This is that guide: how to separate the two products, how to count the ports you actually need, and an eight-row scoring matrix written as questions to put to a supplier rather than specifications we invented. Standards and documentation claims trace to IEEE 802.1 and 802.3, ASAM, AUTOSAR, the IETF and public Linux and Wireshark documentation. Written by the GSAS Micro Systems engineering team in India.
The T1 Family Explained: 10BASE-T1S to Multi-Gig 802.3ch
The T1 family is the set of single-pair Ethernet physical layers used in vehicles, and every member is documented separately inside a different datasheet. This guide puts all of them in one table with rate, symbol rate, line code, specified reach and cabling traced to public IEEE task force documents, then answers the two questions that keep coming back: why 100BASE-T1 has no auto-negotiation, and why one end has to be master. Written by the GSAS Micro Systems engineering team in India.
CAN vs Automotive Ethernet: When to Use Each
CAN and automotive Ethernet answer different questions, so the useful comparison is a decision table rather than a winner. This guide from GSAS Micro Systems sets CAN and CAN FD figures from CAN in Automation next to the IEEE 802.3bw objectives for 100BASE-T1, covers arbitration against switch queues, cost and harness consequences, failure modes on both sides, and what changes on an India bench team's setup when a project adds Ethernet next to the CAN it already runs.
Buying Automotive Ethernet Test Gear in India
Search for a 100BASE-T1 tap or a T1 to RJ45 media converter from India and the results are fibre media converters and LAN cable testers, none of which are T1, and no forum thread that has been through the purchase. This is the missing page: the capability table for a first bench with a defer-or-borrow column, an honest account of what is stocked here versus imported to order, the parts that make up a landed cost as a structure rather than a number, and the compliance portals your teams will actually use. No prices, no duty rates and no lead-time bands, because all three change and none of them belong in an article. Written by the GSAS Micro Systems engineering team in India.
CAN-to-Ethernet Gateways and Tunnelling Legacy Buses
One word, two jobs. A CAN-to-Ethernet gateway either carries a frame across an IP network unchanged, for loggers and remote benches, or stops the frame and re-expresses its signals as service calls. The two have different failure modes, different timing costs and different questions to ask a supplier. This article separates the jobs, states what open documentation actually shows about encapsulation and configuration, and gives a checklist you can put to a vendor.
