CAN / ECU Testing
Automate CAN-based ECU testing without losing the engineer in the loop
A CAN or ECU test procedure is never just "send a frame." It is acquire the interface, send only the approved message, watch the gateway or ECU response, capture evidence, and release the bus cleanly. Every one of those steps is usually done by hand, on a laptop, by whoever is free that day.
Release-gate CAN captureExample run
- Commanded pressure
- 38.2 bar
- Measured pressure
- 37.9 bar
- Gateway dropouts
- 0
- Decision
- release evidence ready
The workflow today
- 01Attach the adapter and bring the bus up manually before every run
- 02Hand-craft or replay raw frames from a DBC, one test at a time
- 03Watch signals in a scope tool and decide pass/fail by eye
- 04Write up what happened afterward, from memory or screenshots
With Plotune Nexus
- 01Acquire the CAN interface as a bounded operation, released when the run ends
- 02Encode and send only the approved message from your DBC, at the required cycle time
- 03Gate the next step on a decoded signal condition instead of a fixed wait
- 04Package the run as one reviewable artifact: trace, decoded signals, and verdict together
