Modern commercial vehicles require advanced functions, tighter control, and faster updates — all driven by software. This shift from mechanical systems to software-defined architectures is accelerating across the industry.
With functions becoming more complex and interdependent to fulfil new requirements, the boundaries between mechanical, electrical, and software domains are increasingly blurred. In this context, the challenge isn’t just designing each component independently, it’s ensuring the entire system functions cohesively and transparently. This becomes even more complex, when having to manage the various configurations and variants within a commercial vehicle. As architectures grow more complex and timelines compress, visibility and alignment across domains become critical to delivering reliable and mature vehicles on schedule.
For component developers, integration managers, and product line managers, this means managing architectural interdependencies at a scale that stretches the limits of traditional PLM and ALM systems. These systems capture data well, but they often lack architectural context, cross-domain traceability, and real-time impact visibility. As a result, teams struggle to assess maturity, anticipate ripple effects, and steer development based on facts rather than assumptions.
As a result, teams are often building blind. Architecture data is fragmented across incompatible platforms. Dependencies remain hidden in engineering silos.
The impact is felt across core workflows. Diagnostic traces are disconnected from the systems they describe. Each software release increases the risk of late-stage integration issues. Architectural opacity has become a systemic liability.
The consequences are visible across major programs:
Leading R&D organizations aren’t trying to patch over the gaps. They’re tackling the root cause: the absence of an engineering intelligence layer that makes architectures transparent, traceable, and steerable.
SPREAD adds this missing layer — not by replacing PLM, but by enhancing it.
The Product Twin acts as a dynamic, real-time model of how systems, functions, and signals interact across the architecture. It brings context, clarity, and decision-ready insight into existing engineering environments.
But visibility isn’t enough. Teams also need solutions to act. That’s where SPREAD’s three core applications come in:
Product Explorer
Enables architecture, system, and component engineers to visualize every function, signal, ECUs and their dependencies. Teams can proactively detect integration risks, trace communication flows across variants, and reduce ambiguity during specification and validation. Discover more about Product Explorer.
E/E Inspector
Provides testing experts and engineers with precision diagnostics. It aligns trace data with configuration specific architectures to surface signal mismatches, test execution gaps, and root causes, reducing diagnostic time by up to 75%. Learn how E/E Inspector works.
Action Tower
Gives product line managers and integration leaders real-time dashboards tracking maturity, ticket curves, data quality, and change impact. It replaces static reporting with dynamic, role-specific insights for engineering and program control.
Together, these tools enable engineering leadership to manage SDV programs as interdependent systems, not fragmented task lists.
One major European OEM deployed SPREAD to manage architecture readiness across its next-gen vehicle line. Within 90 days, they:
These outcomes were not achieved through process optimization. They were the result of restoring architectural visibility.
As SDV programs grow more complex, commercial vehicle OEMs are confronting the limitations of legacy PLM systems that were never built for live, interconnected software-first development.
SPREAD addresses that gap. It creates the architectural transparency needed to manage modern vehicle complexity, at scale, across teams, and without rewriting existing toolchains.
