Signals Table

Everything there is to know about a signal.

All information in one place: start bit, length, byte order, factor, offset, computed physical value, custom attributes, receivers. Sortable and filterable on any field.

Communication Matrix

The network's relationships, at a glance.

ECU × frames view: who transmits, who receives. ECU × ECU view: how many frames are exchanged between each pair of nodes. Two complementary views to understand the full network architecture.

Merge with Conflict Resolution

Merge without losing data.

Merge two databases with automatic conflict detection. For each conflicting frame: keep the base, use the incoming, or merge signal by signal.

CAN Bus, DBC & ARXML: The Formats Behind Automotive Network Data

Behind every CAN frame lies a precise structure — defined by a DBC or ARXML file your tool needs to parse without choking. DBC covers messages, signals, units and enumerations. ARXML handles the full AUTOSAR communication stack. K-Matrix Studio supports both — including the undocumented OEM variants that nobody writes specs for.

Decoding a CAN Log File: IDs, DLC and Intel vs Motorola Endianness

Opening a raw .log or .blf shouldn't require a PhD in binary voodoo. K-Matrix Studio handles Intel and Motorola endianness, factor/offset decoding, and multi-gigabyte logs without breaking a sweat — including the quirky exports from certain OEM tools. Spoiler: if the decoding looks wrong, it's probably not your file.
