What Is ASAM MDF? The Definitive Guide

Who Uses ASAM MDF in Production Today

What Is ASAM MDF? The Definitive Guide | Page: 4 of 4 | Previous: Page 3: What Changed in ASAM MDF 4.3 for ADAS Data (September 2025)

ASAM MDF is used across the global automotive industry, from OEM test labs to Tier 1 supplier development centers to independent test service providers. The format originated in ECU calibration at Vector and Bosch in the early 1990s and has since expanded to cover every major testing domain. The twenty organizations that contributed to MDF 4.3 include automotive OEMs (Audi, BMW, Mercedes-Benz, Porsche), measurement tool vendors (dSPACE, ETAS, IPETRONIK, Kistler, Vector Informatik), data management providers (HighQSoft, Peak Solution), automation and diagnostics companies (Accurate Technologies, iASYS, RA Consulting), and test system integrators (AVL, ViGEM). Their participation in the standard's development is itself evidence of MDF's production relevance; these organizations contribute because their customers demand MDF support.

Adoption extends well beyond the contributing organizations. Every major ECU measurement and calibration tool either uses ASAM MDF as its native recording format or provides importers and exporters. ASAM MDF has become the de facto standard for measurement and calibration systems, as ASAM describes it, but the format now serves far more than the ECU calibration niche where it began.

Who uses ASAM MDF?: ASAM MDF connects recording, analysis, automation, and governance

Powertrain test benches at automotive OEMs record engine performance data in MDF. NVH labs store accelerometer and microphone array data in MDF. Vehicle dynamics teams record steering, acceleration, and GPS trajectories in MDF. Crash and safety departments archive high-frequency sensor recordings in MDF. Durability teams store strain gauge data and classification results in MDF. ADAS development groups are now beginning to record radar, LiDAR, and camera data in MDF 4.3. The ASAM MDF format spans the entire testing lifecycle, from individual sensor measurements to full vehicle validation campaigns.

Organizations that manage their MDF data through ASAM ODS systems include Audi, BMW, Bosch, Cummins, Ford, Honda, and Volkswagen. The data volumes are substantial; test campaigns at large OEMs generate terabytes of MDF files per month, making efficient import, compression, and indexing essential for practical data management.

What MDF Tools and Libraries Support the ASAM MDF Format

What MDF Tools and Libraries Support the ASAM MDF Format

The ASAM MDF tools ecosystem is one of the format's strongest practical advantages for engineers evaluating measurement data formats. Engineers who adopt ASAM MDF gain access to a broad and mature set of commercial and open-source MDF tools spanning recording, analysis, validation, and programming. The table below lists the major MDF tools and libraries as of mid-2026.

Among the major MDF tools, Vector (CANape, MDF4 Lib) and ETAS (MDA) document MDF 4.3 support with the new ZStandard and LZ4 compression algorithms. Other vendors contributed to the standard but have not yet announced MDF 4.3-specific features in their products. The asammdf Python library, which serves as the de facto open-source entry point for MDF work in Python, supports MDF 4 generically but does not yet confirm full MDF 4.3 support for the new block types (DSBLOCK, CLBLOCK, CVBLOCK, CUBLOCK). Engineers working with MDF 4.3-specific features (dynamic data, Raw Sensor Logging) should verify tool support on a case-by-case basis until the ecosystem matures.

The ASAM ODS Support column shows which tools also act as ASAM ODS clients that read managed data directly from an ODS server. Analysis environments such as AVL Concerto, imc FAMOS, jBEAM, and NI DIAdem read both MDF files and ODS-managed data, which is where the recording format meets the management layer.

The breadth of the MDF tools ecosystem is a practical differentiator when comparing ASAM MDF to alternative formats. A test engineer can record data with CANape, explore it with the free MDF Viewer, analyze it with MATLAB or Python (via asammdf), automate analysis with HighQSoft's Merlin Analysis Server, and archive it in an ASAM ODS server such as HighQSoft's AReS Libertas, all using the same MDF format throughout. This seamless toolchain is the result of thirty years of MDF tools ecosystem development and ASAM's governance model, which ensures that tool vendors implement the same specification.

How HighQSoft Integrates ASAM MDF into Test Data Management

How HighQSoft Integrates ASAM MDF into Test Data Management

HighQSoft integrates ASAM MDF into test data management as the management layer that receives MDF data from any recording tool, combines it with metadata from other sources, and makes the complete dataset searchable, governed, and analysis-ready. HighQSoft does not make recording tools or analysis frontends. This positions HighQSoft at the critical junction between data acquisition (where MDF excels) and data management (where ASAM ODS excels).

A central design principle is flexibility with MDF sources. HighQSoft's ModelMapper (MoMa) handles MDF4 files from any tool, any version, and any domain. Whether the MDF file was recorded by Vector CANape during an ECU calibration session, by ETAS INCA during emissions testing, by an IPETRONIK mobile logger during a durability campaign, or by a custom ADAS data logger during autonomous driving validation, ModelMapper imports the data into ASAM ODS using the same rule-driven ETL framework. Approximately 455 built-in rules across fourteen packages handle the transformation from MDF channels and metadata to ODS entities, adapting to the target ODS application model. Custom Java rules extend the framework for organization-specific requirements.

Who uses ASAM MDF?: The ASAM MDF Format in the pipeline for ASAM ODS-based Test Data Management

ModelMapper combines MDF mass data with external metadata (test orders, project assignments, calibration records, ambient conditions) during import, creating fully contextualized ODS records that are findable through structured queries and compliant with governance requirements. HighQSoft's Merlin Analysis Server can trigger ModelMapper imports automatically, then execute analysis jobs on the imported data using Python, MATLAB, Java, or Spark, and store the results back into ODS. This creates a closed loop from MDF recording to managed, analyzed, governed data, running without manual intervention.

The three integration patterns (import, reference, and storage) accommodate different organizational needs. Import converts MDF data fully into ODS entities for active analysis and governance. Reference mode creates ODS metadata pointing to external MDF files, making archived recordings findable without copying mass data. Storage mode manages MDF files as attachments within ODS. In practice, organizations combine these patterns, using full import for actively analyzed data and reference mode for archived recordings that need to be findable but are accessed infrequently.

Imported MDF data follows HighQSoft's "One Language, Every Tool" principle. HQL, one SQL-like query language, reaches the data from Python (via pyHQL), from MATLAB (via the ASAM ODS Toolbox), and from the ASAMCommander web portal in the browser. The ASAM ODS Toolbox for MATLAB provides direct MATLAB connectivity to MDF data imported into ODS, a capability no other TDM vendor offers, used in production at BMW, Bosch, Cummins, and Ford. Engineers can also query imported MDF data in plain English by connecting Claude or ChatGPT through HighQSoft's MCP Server, a production product available today.

Frequently Asked Questions About ASAM MDF

Frequently Asked Questions About ASAM MDF

These are the questions engineers ask most often about ASAM MDF, the tools that support it, and how it fits a test data management strategy.

Is ASAM MDF a modern format?

Yes. ASAM MDF 4.3, released in September 2025, is the latest version, developed by the ASAM MDF working group to address current industry challenges including autonomous driving sensor data, Ethernet-based communication, and high-performance compression. The standard has been continuously updated since its ASAM adoption in 2009, with major revisions in 2012 (compression, bus logging), 2019 (column-oriented storage), and 2025 (ADAS, dynamic data, ZStandard/LZ4). ASAM MDF is not a legacy format; it is an actively evolving standard governed by the organizations that rely on it.

Can ASAM MDF store autonomous driving data?

Yes. ASAM MDF 4.3 adds native support for camera, radar, and LiDAR data through the Raw Sensor Logging associated standard. Dynamic data support (DSBLOCK, CLBLOCK) handles variable signal counts per frame, which is common in radar object lists and LiDAR point clouds. GNSS Data Storage standardizes positional data with privacy tagging. SOC Data Logging handles SOME/IP communication over Ethernet. These capabilities make ASAM MDF 4.3 suitable for ADAS and autonomous driving validation workflows.

Is ASAM MDF only for automotive?

ASAM MDF originated in automotive ECU calibration, and the automotive industry remains its primary domain. However, the format has no technical limitation that restricts it to automotive use. Any domain that records physical measurement data (time-series signals from sensors, test equipment, or data loggers) can use ASAM MDF. The format is used in adjacent industries including aerospace testing, industrial equipment testing, and battery testing. Its standardization under ASAM, which focuses on automotive and mobility, means the associated standards (bus logging, ADAS) are automotive-specific, but the core format is domain-independent.

How do I read ASAM MDF files in Python?

The asammdf library (available on PyPI and GitHub) is the de facto open-source Python library for reading and writing MDF files. It supports MDF versions 2, 3, and 4, handles large files with thousands of channels, and exports to pandas DataFrames, HDF5, MATLAB, CSV, and Parquet formats. For MDF data that has been imported into an ASAM ODS system, HighQSoft's pyHQL library provides Python access using the HQL query language, enabling structured queries across the full managed dataset.

What is the difference between ASAM MDF 4.2 and MDF 4.3?

ASAM MDF 4.3 adds three headline capabilities. Raw Sensor Logging brings native ADAS sensor data support, dynamic data handles variable signal layouts per record, and ZStandard and LZ4 add fast modern compression. ASAM MDF 4.3 is backward compatible with MDF 4.2, and the full feature set is detailed on Page 3 of this guide.
