Volcano Network Architect (VNA)

Volcano Network Architect (VNA) is a CAN and LIN communication design tool that supports system engineering development processes. VNA is a standalone tool suitable for integration in legacy design processes, as well as the ideal foundation for building a system engineering-based communication design process. VNA connects easily to other tools, e.g., enterprise-wide communication databases.

Features

Design Features

  • Automatic and/or manual creation of the communication matrix based on signal timing requirements.
  • Automatic and/or manual gateway definitions
  • Automatic and/or manual schedule table definitions
  • Definition of “fixed” nodes to facilitate handling of “carry over” ECU designs.

Connectivity and General Features

  • Connect to other tools through its import/export interface supporting FIBEX XML, LIN Node Capability File, .dbc
  • Version and variant management of ECUs, signals etc.

Analysis Features

  • Verify that timing requirements of individual signals and/or complete frames are fulfilled by the network design
  • Special support for “framebased” timing to support legacy ECUs where no signal timing information is available.
  • End-to-end timing analysis for data, over several gateways if required.
  • Detects if there is risk for dataloss, like frame being overwritten at the receiver or transmitter.
  • Consistency checks of the communication system

Highlights

Requirements capturing

  • Store communication requirements for signals, nodes, functions

Automated communication design

  • Signal packing
  • Frame identifier assignment
  • Gateway routing

Timing analysis

  • Guaranteed message latencies, even for gatewayed signals over any number of gateways

Consistency checking

  • Ensures errors are captured as early as possible in the process

Measures architecture's feasibility

  • Bus utilization
  • Timing requirements
  • Implications of adding carry-over ECUs

Increasing productivity and improving quality

VNA enables an increase in the productivity of communication design and testing processes, while at the same time improving end-result quality.

  • High level requirement-capturing in the early design phase
  • Implemented timing model to obtain guaranteed message latencies
  • Automatically maps signals into frames for better use of network bandwidth
  • Perfect filtering of frame IDs to lower the interrupt load of the CPU
  • Automatic and seamless gatewaying to minimize interrupt load of certain ECUs

In the end, the above points result in a more robust design of the communication system, improving quality of the end product while at the same time improving the efficiency of the design and testing process.
