Modeling and Simulation for Network Signal Integrity Design
Designing and managing multiple networks connected to a hundred computers, and exchanging thousands of signals, can lead to a complexity nightmare.
The complexity of in-vehicle networks such as CAN creates significant challenges to verify a network’s physical layer signal integrity. The building of traditional physical prototypes to test the network against its system specifications is expensive.
Based on the IEEE standard language VHDL-AMS, the SystemVision virtual design environment provides hardware modeling capabilities that are well suited for CAN SI analysis.
- Model the analog, digital, and mixed-signal aspects of the transceivers
- Model the behavior of twisted-pair transmission lines, connectors, and other components of the CAN physical layer
SystemVision supports both VHDL-AMS as well as traditional Spice modeling methods.
Examples of Simulation-based Techniques
- Analysis of static and dynamic features of transceivers, lines, and other components
- Examining termination strategies
- Characterizing data delay vs. intermediate-note stub-length
- Assessment of electrostatic discharge protection capability of transient voltage suppression components
