Calibration, measurement and visualization of embedded control systems

Sumac is an efficient tool used for calibration, measurement and visualization of embedded control systems or ECUs. It works either offline or in real-time via XCP communication or DBC-based CAN measurement.

The intuitive and lightweight interface makes it ideal during software development, calibration, testing and validation. It is intended for all stages of the development cycle.

Automatic reload of the A2L file simplifies testing scenarios when frequently using a new software release, for example in when building rapid prototypes or when the team works according to agile processes.

Measurement of CAN networks

Sumac can also measure and record CAN networks defined by DBC files. Any number of CAN networks can be monitored simultaneously as and XCP session is active. Signals defined in a DBC file and XCP measurements can be shown in the same plot, written to the same recording file etc.

Node-locked license management

Describes how to add a node-locked license to a computer.

Node-locked license

This license model ties a license to a single computer. No additional hardware is required. Follow the steps below to activate your license.

  1. Start CodeMeter Control Center.
  2. Choose File->Import License… and select <Product>.WibuCmLIF (included in the delivery package).
  3. Select the CmActLicense imported in previous step and click License Update. See screenshot for example.
  4. A wizard will be started. Use the wizard to create a license request. Send the exported license request file to
  5. In return from you will get a license update file. Use the same wizard for importing this license update files as you used to create the license request.

Evaluation license management

Describes how to add a evaluation license to a computer.

Evaluation license

This license model ties a license to a single computer. No additional hardware is required. Follow the steps below to activate your license.

  1. Send a mail requesting a trial license to In return you will get a license update file.
  2. Start CodeMeter Control Center.
  3. Choose File->Import License… and select the license update file you got from 


System requirements

  • Windows 10 or later.
  • For CAN a CAN device is required. Sumac supports ETASKvaser and PEAK-System and Vector CAN devices. 
  • We are an authorized distributor for Kvaser and can therefore deliver complete measurement solutions including both software and hardware. From Kvaser we recommend the Semipro or Pro series. Note that we do not recommend the any of Light variants from Kvaser due to their limited capacity to handle high bus loads.
  • ASAP2 (.A2L) file required. See Acam toolsuite for A2L creation and management.
  • ECU with XCP 1.0 or later (for real-time operation only).



There is no installation wizard. Just download and unzip the archive to a folder of your choice.

Sumac 1.3p8 for Windows

If you’re interested in builds for Linux or MacOS – contact us!


Sumac uses Codemeter for license management. Hence Codemeter runtime is required. If it isn’t already installed get it from

Sumac for Windows needs Microsoft Visual Studio Redistributable. Download and install vc_redist.x64.exe if it isn’t already installed.

CAN device drivers

Due to the large number of CAN device vendors supported Sumac doesn’t come bundled with CAN device drivers. Below follows links to the drivers for each supported CAN device vendor.

First the driver for the device itself is needed. The download is a package called Hardware Service Pack. Install this first and then install the driver for your specific device from within Hardware Service Pack.

An addition, the BOA integration package from ETAS is required. During installation choose the 64-bit version since Sumac is a 64-bit exe. The path to the DLLs in the BOA integration package must be manually added to the system PATH. Default folder for  these DLLs is 
C:\Program Files\ETAS\BOA_V2\Bin\x64\Dll\Framework

Download both packages from
