- For
- Electronics engineers designing CAN-FD buses
- Worth noticing
- Its bit check compares differential voltage with each receiver’s threshold at the sample point and reports margin in volts.
Field notes
The workflow starts with a drawn network of backbone, stubs, boards, connectors, and cable segments, then checks voltage at receiver sample points. Users can select linear transceiver models or import IBIS files; filters and protection components are also represented. The site says computation stays on the user's computer, and explicitly positions the simulator as a pre-layout aid—not a replacement for SPICE, measurements, or compliance testing.
