Too many moving layers
ECU variants, software releases, network topologies and environment-specific behaviour change at different speeds.
Automotive communication intelligence
See what changed.
Know what it affects.
K-Matrix Inspector turns complex communication definitions and diagnostic traces into a navigable model of ECUs, buses, messages, signals and routes—so teams can compare versions, verify runtime behaviour and find integration risk earlier.

The engineering problem
Communication complexity grows faster than manual review.
Differences hide in structure
A changed route, removed signal, cycle-time drift or silent consumer impact can be buried across large files and traces.
Teams see different truths
Architecture, integration and test teams often interpret the same communication evidence through separate tools and views.
How it works
Compare K-Matrix versions first. Verify real-world behaviour when needed.
K-Matrix Inspector makes communication change visible across K-Matrix releases, then uses the selected version as the reference for optional system and field-log verification.
Core value pathK-Matrix version intelligence
Load K-Matrix versions
Bring the K-Matrix releases you want to inspect into one controlled, version-aware workspace.

On-demand verification path
Does the implemented system conform to the selected K-Matrix version?
Use integration-system or field-test evidence when you need a rapid answer about actual software behaviour.
01 — SET THE REFERENCE
Select a K-Matrix version and load a BLF or TTL log
The chosen K-Matrix version defines the expected communication behaviour for the analysis.
02 — VERIFY RUNTIME BEHAVIOUR
Compare observed traffic with the K-Matrix version
Check message presence and content, payload or message length, cycle times and timing against the selected version.
Core capabilities
Follow a change from definition to network impact.
Each view answers a specific engineering question while using the same normalized communication model underneath.
01 — VIEW & SEARCH
Navigate the network as a graph, not a spreadsheet.
Explore ECU, bus, message and signal relationships in flat or hierarchical views. Select a node to reveal routes, message definitions, signal mappings and connected consumers.

02 — COMPARE
Make every added, removed and changed element explicit.
Compare complete baselines or focus on one ECU. Drill from bus-level differences to changed messages and signals, then review the affected connections and consumers.

04 — IMPACT & ASSISTANCE
Move from “what changed?” to “what should we check?”
Focus on a selected ECU or change, see affected connections and use context-aware summaries to turn complex deltas into a prioritized engineering review.

Engineering workflow fit
Add focused analysis without replacing established tools.
K-Matrix Inspector works alongside existing engineering environments and adds a dedicated workspace for K-Matrix visualization, version comparison and runtime verification.
Fits existing engineering workflows
Architecture and communication-design environments can remain the source of design intent. K-Matrix Inspector adds a version-aware analysis layer for comparison, routing inspection and runtime verification without forcing teams to replace their established authoring workflow.

Where to use it
Built for the moments when communication risk becomes delivery risk.
Build-to-build regression
Compare consecutive baselines, classify deltas and focus verification on the messages, signals and consumers that actually changed.
Simulator ↔ test bench ↔ vehicle
Reveal environment-specific communication behaviour and verify expected routes, timing and message presence across test stages.
ECU-focused regression
Focus comparison on a selected ECU and review its incoming, outgoing and connected-message changes across K-Matrix versions.
Pre-delivery evidence
Create repeatable, version-aware analysis that reduces ambiguity between supplier, integration and validation teams.
Expected impact
Less manual trace review. Faster root-cause isolation.
By making structure, behaviour and diagnostic evidence visible in one analysis flow, teams can reduce repetitive review and move issues earlier in the lifecycle.

Frequently asked
Product questions, answered.
Is K-Matrix Inspector only a file-diff tool?
No. File and baseline comparison is one capability. The product also builds a communication topology, maps routes and consumers, verifies measured traces and connects findings to the selected baseline.
What kinds of problems can the verification flow detect?
Depending on the available design and trace data, checks can cover missing or unexpected messages, cycle-time and routing-latency deviations, message-length mismatches, signal-range violations, routing failures and Some/IP consistency findings.
Does it replace architecture authoring tools?
No. It complements architecture and communication-design environments by adding focused K-Matrix visualization, version comparison, routing analysis and runtime validation.
How can it be deployed?
Deployment can be adapted to enterprise constraints, including controlled on-premise environments or scalable hosted execution. Data interfaces, identity, storage and retention should be defined during technical discovery.
