Shulou(Shulou.com)06/03 Report--

With the new requirements of functional safety, AutoSAR, vehicle networking, intelligent driving and so on, the complexity and relevance of current electronic and electrical systems are increasing day by day. At present, the traditional document-based design has been unable to adapt to the increasing demand of electronic and electrical development due to its low reuse, no correlation, no synergy and other shortcomings. Based on Systemweaver platform, Hengrun provides vehicle-level electronic and electrical system collaborative design solutions to help customers establish electronic and electrical R & D platforms, improve engineers 'collaborative development efficiency and ensure product R & D quality.

product introduction

Systemweaver software is an enterprise-oriented electronic and electrical collaborative R & D platform tool developed by Sweden Systemite Company. Support electronic and electrical system R & D V process, design, analysis, verification and management of electronic and electrical systems from demand-function-system-ECU-test and other multi-stage, and can trace and associate the whole process data of the system to ensure the correctness, consistency and effectiveness of the data. Enterprises can customize and develop Systemweaver models according to their own product needs, and customize software function modules through model configuration.

In addition, Systemweaver provides a fully real-time collaborative development environment that ensures collaborative R & D between engineers in different fields through flexible issue management mechanisms and improves enterprise communication efficiency.

product features
