SystemVision CAN SI

CAN Network SI

Easier CAN Analysis

SystemVision CAN SI automates key analyses for CAN network design.

SystemVision CAN SI harnesses the power of SystemVision multi-discipline simulation in a specialized, easy-to-use package. Network Designers quickly analyze the CAN physical layer to validate topologies and variants, early in the development process, without building physical prototypes.

SystemVision CAN SI automatically models and simulates the analog, digital, and mixed-signal performance of a communication bus, including transceivers, twisted-pair transmission lines, network connection topologies, and other components and characteristics of the CAN physical layer, capabilities well beyond the manual calculation and prototyping tasks of the traditional network design process.

SystemVision CAN SI Explained

SystemVision CAN SI plays a key role in the challenge of verifying signal integrity for CAN network applications that span automotive (ISO 11898-2), commercial vehicle (SAE J1939), and agricultural equipment (ISO 11783). Component “recommended use” and standard network configuration guidelines provide for an overly conservative design that can be at odds with weight, cost, and layout constraints.

With an easy-to-use, Microsoft Excel-based design entry mechanism, SystemVision CAN SI automatically generates the network design, configures data and communication sequences, runs the simulation, performs key CAN bus measurements, and captures pertinent analysis results in a simple go/no-go spreadsheet format. SystemVision CAN SI helps design teams with the important network development tasks of signal characterization, parametric analysis, and EMI characterization and suppression.


Signal Characterization

Simulate line loss in long transmission lines, determine sound termination strategies to mitigate stub reflections, and analyze the effect of delay on data synchronization—all under the full range of operating conditions and customer configuration options.

Parametric Analysis

Sweep key system parameters and run multiple simulations to capture large sets of experimental data and determine important system parameter dependencies. Analyze design tradeoffs to optimize network performance and create the most cost-effective bus configurations. Determine optimal lengths for intermediate node stubs.

EMI Assessment

Assess overall EMI characteristics for any CAN bus configuration. Analyze EMI-causing common-mode currents on differential lines. Quantify the effects of transient disturbances, including communication errors caused by electrostatic discharge.
