COSYM Releases

COSYM (CO-simulation of SYsteMs) is the powerful simulation and integration platform from ETAS. It is providing a state-of-the-art approach for MiL/ SiL use cases. We are constantly working to improve your COSYM experience. By providing quarterly updates, we are able to provide improvements in frequent and short cycles. On this page we give you an overview of our updates as they are available for you.

COSYM V3.0.0

The COSYM V3.0.0 release is the first release with focus on pure virtualization use cases and automation.  

Highlights from COSYM V3.0.0 are the following

  • Renovated COSYM appearance and workflow to satisfy MiL/SiL use case only
  • Enabled SiL API to connect 3rd party tooling to COSYM simulation
  • Enabled workflow from COSYM-CAR to COSYM for restbus model generation (signal level) as FMU based on ARXML file
  • ASAM-XIL: Enabled with downsampling API 
  • ASAM-XIL: Enabled with Continuous Mode block
  • ASAM-XIL: Supported with .olc4 type for MA Port setup
  • Specification of Regular Expression to provide an easy way for renaming ports to match the criteria for automated connection creation
  • Specification of the initial values for the outports and inports of all model instances in a system to get proper starting values and calculations at simulation start
  • Support of references inside the MATLAB®/Simulink® models 
  • Support of INCA V7.3.6

Technical requirements necessary for the operation of COSYM V3.0.0 can be found here.

COSYM V3.0.0 is compatible with

  • INCA V7.3.6 for the SiL use case to enable simulation-based calibration (support of INCA V7.2.6, V7.3.5)
  • ASCMO-MOCA for calibration in the SiL use case. Versions 5.8 and higher are supported
  • MATLAB® from version 2016a - 2020a for the integration of Simulink® models, as well as for co-simulation with Simulink®

For a complete overview of all improvements, and more details please see release notes.
