What Is ASAM MDF4 and Why Is It Used?

Fri, 14 Aug 2026 13:07:33 -0400

Part 1 - ASAM MDF4 Explained

Modern vehicle development generates enormous amounts of measurement data. Whether engineers are calibrating an ECU, validating a control strategy, testing a powertrain, or recording data from a vehicle network, hundreds or even thousands of signals may need to be captured simultaneously.

Storing those measurements is only part of the challenge. The data also needs context: What does each signal represent? What are its units? How should a raw value be converted into a physical value? When was each sample recorded? How are signals with different sampling rates synchronized?

This is where ASAM MDF (Measurement Data Format) comes in.

MDF is a standardized binary file format designed for storing measurement data together with the information required to interpret it. MDF4, the fourth major generation of the standard, was designed to support the increasingly large and complex datasets produced by modern automotive development and testing.

What Is ASAM MDF?

MDF stands for Measurement Data Format. The standard is maintained by ASAM (Association for Standardization of Automation and Measuring Systems) and is widely used for measurement and test data, particularly in automotive development.

An MDF file is more than a collection of recorded values. It can contain both the measurement samples and metadata describing those measurements.

Depending on the recording, this can include information such as:

Signal and channel names
Raw measurement values
Physical units
Conversion information
Time information
Sampling information
Descriptions and other channel metadata
Events and attachments
Vehicle network data

Keeping this information together makes MDF useful for exchanging measurement data between acquisition, calibration, validation, and analysis tools.

Files based on MDF 4.x commonly use the .mf4 file extension.

Why Does a Standard Measurement Format Matter?

Consider a relatively simple test.

An engineer records engine speed, temperatures, pressures, pedal position, ECU parameters, and CAN traffic during a vehicle test. Some measurements may be sampled every millisecond, while others are recorded much less frequently.

A simple tabular format can represent some of this information, but it quickly becomes inefficient as recordings become larger and more complex.

There are several questions the file format needs to answer.

How do signals with different sampling rates coexist? How are timestamps represented? How is a raw ECU value converted into an engineering unit? How can very large recordings be stored efficiently? How can another application interpret the recording without knowing the details of the original acquisition system?

MDF was created to provide a standardized way of representing this type of measurement data.

That standardization is important because the application recording the data does not necessarily have to be the application analyzing it.

Why MDF4?

Earlier versions of MDF had already established the format within automotive measurement and calibration workflows. However, measurement systems continued to evolve.

ECUs became more complex. The number of measurable parameters increased. Vehicle networks generated more data. Sampling rates increased. Test durations became longer.

As a result, measurement files could become extremely large.

MDF4 introduced an architecture better suited to these requirements while retaining the core idea behind MDF: store measurement data together with enough information to correctly interpret it.

One of the key characteristics of MDF4 is its block-oriented structure.

Instead of treating a measurement file as one large table, MDF4 organizes information into interconnected blocks. Different blocks can describe the file, data groups, channel groups, individual channels, conversions, actual measurement data, events, attachments, and other information.

This architecture gives MDF4 considerable flexibility.

For example, a recording can contain multiple groups of measurements with different structures and timing characteristics rather than forcing every measurement into one universal sample rate.

We'll look much more closely at this block structure in the next article in this series.

MDF4 Is More Than Signal Values

When engineers first encounter an MF4 file, it is easy to think of it as simply a container for signal-versus-time data.

There is considerably more happening underneath.

Imagine that a measurement system records an ECU parameter as the integer value: 2150

That number alone may not tell an engineer very much.

The MDF4 file can also describe the channel, its unit, and the conversion needed to turn the stored value into a meaningful physical value.

The result might be something such as: 21.5 °C

This distinction between stored/raw values and physical engineering values is fundamental to working with measurement data.

MDF4 can preserve the information needed to make that interpretation part of the dataset rather than relying entirely on external knowledge.

Handling Different Sampling Rates

Another important measurement challenge is time.

Not every signal in a vehicle or test system is acquired at the same rate.

For example:

One group of signals might be sampled every 1 ms.
Another might be sampled every 10 ms.
A slower temperature measurement might update every 100 ms.
Network messages may arrive according to their own timing.

Trying to force all of this information into one large table can result in duplicated timestamps, empty values, interpolation, or unnecessarily large files.

MDF4 provides structures that allow related channels and their timing information to be organized efficiently.

This is one reason understanding concepts such as data groups, channel groups, channels, and master channels becomes important when working with MDF4.

Designed for Large Measurement Files

Measurement files can grow quickly.

Recording 1,000 channels at high sampling rates for an extended test can generate millions (or billions) of individual samples.

MDF4 includes mechanisms intended to make storing and accessing these datasets practical. Among them are support for compressed data blocks and structures that allow measurement data to be organized according to how it was acquired.

These features also introduce an important distinction between MDF4 and simpler formats such as CSV.

CSV is extremely useful when data needs to be human-readable or easily exchanged with general-purpose applications. But representing a large, complex measurement recording as rows and columns can significantly increase file size and lose some of the richer structure associated with the original measurement.

MDF4 was designed specifically around measurement data.

Where Is MDF4 Used?

MDF4 is particularly common in automotive engineering, although its underlying concepts apply to other measurement environments as well.

Typical applications include:

ECU calibration
Vehicle testing
Powertrain development
Electrified powertrain and battery testing
Controls development
Validation and verification
Data acquisition
Vehicle network recording
Test bench measurements
Measurement data exchange and post-processing

A common workflow might look like:

Measurement → MDF4 recording → Analysis → Engineering decision

The recording application captures the test in MDF4, and engineers can then use an MDF4-compatible analysis application to inspect signals, compare tests, calculate derived quantities, or investigate events.

For example, ATI VISION Data Analyzer (VDA) can work with MDF4 measurement files for post-processing and analysis, including MDF4 files generated by third-party measurement systems. This illustrates one of the practical advantages of using a standardized measurement format: acquisition and analysis do not necessarily need to happen in the same software environment.

MDF4 vs. MDF3

MDF3 files are still encountered in existing measurement environments, so it is useful to understand that MDF4 is not simply MDF3 with a new file extension.

MDF4 introduced substantial changes to the underlying file architecture to better accommodate modern measurement requirements, including increasingly large and diverse datasets.

For users, both formats may ultimately present familiar concepts, channels, timestamps, values, and units.

For software reading the files, however, their internal structures are significantly different.

This becomes especially important when developing data-processing tools or troubleshooting why a particular application handles one MDF generation differently from another.

Why Engineers Should Understand MDF4

Most engineers working with MF4 files will never need to implement an MDF4 parser.

But understanding the basic structure of the format can still make everyday data analysis easier.

It helps explain why two signals may have different time bases, why extracting a channel from a very large recording can involve more work than expected, why raw and physical values can differ, why file compression affects analysis performance, and why converting an MDF4 recording to a simpler format may discard useful information.

Understanding what is inside the file makes it easier to understand what your analysis software is doing with it.

What's Next: Inside an MDF4 File

So far, we've treated MDF4 largely from the outside: what it is, why it exists, and the types of problems it solves.

The next step is to look inside.

In the next article in this series, Inside an MDF4 File: Understanding the MDF4 Data Structure, we'll explore the block-based architecture behind MDF4 and introduce the relationships between file headers, data groups, channel groups, channels, conversions, and the blocks containing the actual measurement data.

Once those relationships are clear, an MF4 file stops looking like a mysterious binary file and starts looking like a structured representation of the measurement system that created it.

Automotive Ethernet Myths: Separating Fact from Fiction

Automotive Ethernet has become one of the most important technologies shaping modern vehicle development. Yet despite its growing adoption, there are still plenty of misconceptions surrounding what it is, what it can do, and how it fits into today's vehicle architectures.

Let's separate some of the most common myths from reality.

Myth #1: Automotive Ethernet Will Replace CAN

Reality: Automotive Ethernet complements CAN. It does not replace it.

One of the biggest misconceptions is that Ethernet is replacing every in-vehicle network. In reality, modern vehicles rely on a combination of communication technologies.

Each serves a different purpose:

LIN connects simple sensors and actuators.
CAN handles reliable, real-time control communication.
CAN FD provides increased bandwidth for larger control messages.
Automotive Ethernet acts as the high-speed backbone for data-intensive systems.

Each network has strengths, and modern vehicle architectures are designed to take advantage of all of them.

Myth #2: Ethernet Is Just Faster CAN

Reality: Ethernet is an entirely different communication architecture.

CAN is message-based. Automotive Ethernet is packet-based.

Ethernet supports:

IP-based communication
Service-oriented architectures
High-bandwidth data streams
Centralized computing
Modern diagnostics

It is not simply a faster version of CAN. It enables capabilities that traditional vehicle networks were never designed to support.

Myth #3: Standard IT Ethernet Tools Are Good Enough

Reality: Automotive Ethernet has unique requirements.

Although Automotive Ethernet is based on Ethernet standards, vehicles introduce additional technologies and protocols, including:

Single-Pair Ethernet
SOME/IP
DoIP
AVB and TSN

Engineers also need visibility across CAN, CAN FD, LIN, gateways, and Ethernet simultaneously.

General-purpose networking tools can provide packet captures, but they typically lack the automotive-specific decoding and mixed-network visibility needed for efficient development and validation.

Myth #4: More Bandwidth Solves Everything

Reality: High bandwidth introduces new challenges.

Moving more data is only part of the equation.

Engineers must also manage:

Latency
Jitter
Synchronization
Gateway routing
Service discovery
Network loading

ADAS systems, for example, depend on camera, radar, and lidar data arriving at predictable times. High bandwidth without proper timing can still result in poor system performance.

Myth #5: Diagnostics Work the Same as They Always Have

Reality: Diagnostics are evolving alongside vehicle architectures.

CAN-based diagnostics remain important, but Ethernet has introduced Diagnostics over IP (DoIP), enabling faster communication and more efficient software updates.

As vehicles become increasingly centralized, diagnostics span multiple networks and often pass through gateways before reaching their destination.

Testing diagnostic communication now involves validating routing, network behavior, and interactions across the complete vehicle architecture.

Myth #6: Ethernet Makes Vehicle Networks Simpler

Reality: Ethernet simplifies architecture, not development.

Zonal architectures reduce wiring, improve scalability, and support centralized computing.

However, they also introduce new engineering challenges.

Development teams must understand:

Mixed-network communication
Service-oriented software
Time synchronization
High-speed packet analysis
Gateway behavior
Multi-network diagnostics

The physical architecture may become simpler, but the software and communication layers become more sophisticated.

Myth #7: One Tool Can Solve Every Problem

Reality: Modern development requires an integrated toolchain.

Developing and validating today's vehicles involves multiple activities, including:

Network analysis
ECU interaction
Diagnostics
Gateway testing
Simulation
Data logging
Validation

Rather than relying on a single tool, engineers benefit from solutions that work together throughout the development lifecycle.

For example, CANLab provides visibility into communication across CAN, CAN FD, LIN networks. VISION supports ECU interaction and development workflows, while ATI's Vehicle Communication Gateway helps engineers bridge and validate communication between mixed-network architectures.

The Real Story

Automotive Ethernet is not replacing every existing technology.

It is enabling a new generation of vehicle architectures built around centralized computing, zonal networking, software-defined functionality, and advanced driver assistance systems.

CAN, CAN FD, LIN, and Automotive Ethernet each have a role to play. Understanding how they work together, along with the right tools to develop and validate them, is what allows engineers to build reliable, scalable vehicle networks.

Series Recap

Throughout this series, we've explored:

Why Automotive Ethernet became necessary
How it works alongside CAN and CAN FD
The protocols that power modern vehicle communication
The rise of zonal architectures
Development and validation challenges
The tools engineers use to build and test modern vehicle networks

As vehicles continue to evolve, Automotive Ethernet will play an increasingly important role. But success won't come from adopting a single technology. It will come from understanding how the entire vehicle network works together.

Whether you're developing, testing, or validating mixed-network vehicle architectures, ATI provides an ecosystem of software and hardware solutions designed to support every stage of the workflow. From CANLab for network analysis to VISION for development and validation, and the Vehicle Communication Gateway for protocol translation and mixed-network communication, ATI helps engineers simplify the complexity of modern vehicle networks.

Automotive Ethernet Explained Pt. 6

Getting Started with Automotive Ethernet Tooling

Automotive Ethernet introduces new capabilities, but it also introduces new tooling requirements.

CAN tools are still important, especially in mixed-network vehicles, but Ethernet adds packet-based communication, IP diagnostics, service discovery, synchronization, and high-bandwidth data streams. Engineers need tools that can see more than raw traffic. They need tools that understand how Automotive Ethernet behaves inside the vehicle.

Why Tooling Matters

Automotive Ethernet networks are more complex than traditional CAN networks.

Instead of only looking at message IDs and signal values, engineers may need to analyze:

Ethernet frames
IP traffic
SOME/IP services
DoIP diagnostic sessions
AVB or TSN timing behavior
Gateway routing
CAN, CAN FD, and LIN interaction

Without the right tools, it can be difficult to understand where a problem starts and how it affects the rest of the vehicle network.

What Engineers Need on Day One

Getting started with Automotive Ethernet typically requires a few core capabilities.

At minimum, engineers need to be able to:

Connect to Automotive Ethernet networks
Monitor live traffic
Decode common automotive protocols
Log data for later review
Generate or stimulate traffic
Validate diagnostics over Ethernet
View CAN and Ethernet behavior together

The goal is not just to capture packets. The goal is to understand what the vehicle network is doing.

Engineers also benefit from tools that provide a unified view of the vehicle network. As modern architectures combine CAN, CAN FD, LIN, and Automotive Ethernet, switching between multiple disconnected tools can slow troubleshooting and validation efforts. ATI's VISION® platform helps engineers monitor, analyze, and interact with multiple vehicle networks from a single environment.

Monitoring vs Active Testing

There are two common tooling modes: monitoring and active testing.

Monitoring means observing traffic without interfering with the network.

This is useful for:

Debugging communication issues
Reviewing network load
Capturing intermittent faults
Understanding ECU behavior

Active testing involves sending traffic, simulating ECUs, or injecting faults.

This is useful for:

ECU bring-up
Gateway validation
Diagnostics testing
Stress testing
Reproducing edge cases

Both are important. Development teams often rely on active testing early, while validation teams need strong monitoring and repeatable test execution.

For example, engineers may use ATI's VISION® platform to monitor data that an ECU is receiving from other connected nodes. This can be used to identify message decoding issues in the ECU software. During development, these same environments can be paired with simulation and gateway solutions to actively test communication scenarios and validate system behavior.

Scaling from Bench to Vehicle

Automotive Ethernet testing usually starts on the bench.

A bench setup might include:

One or more ECUs
A gateway
CAN or CAN FD networks
An Ethernet connection
Diagnostic or simulation tools

As development progresses, testing moves into the full vehicle. At that point, complexity increases significantly.

Engineers must validate:

Multi-network traffic
Gateway behavior
Latency and jitter
Diagnostic routing
System-wide fault behavior

As testing progresses from bench setups to full vehicle environments, maintaining consistent workflows becomes increasingly important. Tools that support both development and validation activities help reduce rework and improve efficiency. ATI's portfolio, including VISION® and its Vehicle Communication Gateway, can be used throughout the development lifecycle, from early ECU bring-up and diagnostics to vehicle-level network validation.

Avoiding Common Beginner Mistakes

One common mistake is treating Automotive Ethernet like office Ethernet.

Standard IT tools can be helpful, but they are not enough on their own. Automotive networks require visibility into vehicle-specific protocols, timing requirements, and mixed-network behavior.

Another mistake is testing Ethernet in isolation. In most vehicles, Ethernet works alongside CAN, CAN FD, and LIN. A problem may appear on Ethernet but originate from a gateway, diagnostic route, or CAN-side message.

Effective tooling should help engineers see the whole system, not just one network segment.

What to Look for in Automotive Ethernet Tools

When evaluating tools, look for capabilities such as:

Automotive Ethernet interface support
CAN, CAN FD, and LIN support
SOME/IP and DoIP decoding
Logging and replay
Traffic generation
Gateway testing support
Time synchronization analysis
Fault injection
Scalable bench and vehicle workflows
Unified visibility across CAN, CAN FD, LIN, and Automotive Ethernet networks

Modern vehicle architectures require engineers to understand how multiple networks interact. Solutions such as ATI's VISION® platform are designed to provide that visibility, helping teams analyze communication, diagnose issues, and validate system behavior across the entire vehicle network.

The right tool should support both development and validation needs without forcing teams to switch workflows entirely.

Why This Matters

Automotive Ethernet is becoming a foundation for modern vehicle architectures. As networks become faster and more interconnected, engineers need tools that provide visibility across the entire system, not just individual buses. Platforms such as ATI's VISION® help development and validation teams monitor network activity, troubleshoot issues, and better understand interactions between Ethernet, CAN, CAN FD, and LIN networks.

The better the tooling, the easier it is to debug issues early, validate system behavior, and reduce risk before vehicle-level testing.

Looking to Simplify Automotive Ethernet Development and Validation?

Modern vehicles rely on a mix of CAN, CAN FD, LIN, and Automotive Ethernet networks. ATI's VISION® platform and Vehicle Communication Gateway help engineers monitor, analyze, diagnose, and validate communication across these mixed-network environments, supporting both development and validation workflows from the bench to the vehicle.

Up Next

In the next post, we will look at common Automotive Ethernet myths and what actually breaks in real-world development and validation. From "Ethernet isn't deterministic" to "Ethernet will replace CAN," we'll separate fact from fiction and examine the challenges engineers actually encounter during development.

Scripting: The Secret Ingredient to Smarter Testing

Fri, 06 Jun 2025 12:40:38 -0400

In the world of embedded systems and communication networks, scripting is more than just a coding technique—it's a way to automate, extend, and elevate your testing workflows. Whether you're validating messages on a CAN bus, simulating real-time events, or analyzing system behavior, scripting gives you control.

Why Scripting Matters

At its core, scripting is about flexibility. Unlike rigid interfaces or predefined tools, scripts allow you to define custom logic, react to real-time conditions, and build automated routines tailored to your specific testing environment. From basic automation to complex data analysis, scripting empowers engineers and testers to go beyond the limitations of drag-and-drop GUIs.

With the right scripting environment, you can:

Automate repetitive tasks to save time and reduce error
Respond to dynamic events like incoming messages or signal changes
Simulate real-world conditions through timed or conditional actions
Create reusable workflows that scale across teams and projects
Analyze data in real time without needing to export to other tools

Scripting is what turns a test tool into a test platform.

Enter CANLab: Scripting Built-In

While scripting is powerful, it’s only as effective as the environment that supports it. That’s where CANLab steps in. CANLab includes a full-featured scripting language designed specifically for testing communication networks, with syntax based on the widely-used C# language. This makes it both familiar to developers and accessible to testers with basic programming knowledge.

Key features include:

Customizable Script Editor: Syntax highlighting and editor configuration make it easy to write, read, and debug scripts.
Event-Driven Logic: Trigger functions using On Message Received, On Signal Received, On KeyPress, or On Timer—ideal for creating interactive or automated test scenarios.
Native Execution: Scripts run directly within CANLab for real-time performance and low-latency response.
Data Analysis Support: Go beyond basic message handling—use scripts to evaluate signal conditions, generate summaries, and flag anomalies on the fly.
Portability and Sharing: Save scripts and share them across teams, enabling test engineers to focus on running tests, not building them from scratch.

Build Once, Use Anywhere

One of the most powerful aspects of scripting in a platform like CANLab is the ability to reuse and adapt. Write a script once, and it can be used by multiple groups, across different projects, or even automated into continuous integration workflows. This reduces setup time, standardizes testing, and enhances collaboration.

Final Thoughts

Scripting is no longer a luxury in modern testing—it's a necessity. It brings agility, precision, and insight to test engineers and system developers alike. And with tools like CANLab offering a robust scripting engine out of the box, there's never been a better time to start automating your test workflows.

If you're looking to move faster, test smarter, and unlock the full potential of your communication networks, scripting is the way forward—and CANLab is ready when you are.
