Thirteen engineering tools for vehicle networks, AUTOSAR, diagnostics, functional safety, testing and requirements, built on public standards. Sign in free to start using them.
Enter the bit rate and your messages to see the bus load for classic CAN or CAN FD, with and without worst-case bit stuffing.
Open tool →BITEnter your CAN clock, bit rate and target sample point. You get every valid prescaler and segment setting, best first, with the values to write into the controller registers.
Open tool →DBCTurn raw CAN bytes into physical values, or the other way round. Enter a signal definition, or load a DBC file to decode every signal in a frame.
Open tool →DIFFLoad two versions of a DBC file to see every change between them, or one file to check it for common mistakes: duplicate IDs, overlapping signals, signals outside the payload and ranges the bits cannot carry.
Open tool →ARXMLOpen AUTOSAR ARXML files to browse components, ports and interfaces, check them for common mistakes, or compare two versions to see exactly what changed. A read-only review tool: nothing is generated, nothing is uploaded.
Open tool →ASILRate each hazardous event for severity, exposure and controllability to get its ASIL under ISO 26262, and build a simple hazard list you can export.
Open tool →SPFMEnter your failure modes with FIT rates, safe fraction and diagnostic coverage. You get SPFM, LFM and an estimate of PMHF, checked against the targets for your ASIL.
Open tool →CRCCalculate CRCs with the algorithms from the AUTOSAR CRC library that the E2E protection profiles use, from hex bytes or text.
Open tool →UDSPaste a UDS message to see what it means, look up a negative response code, convert a DTC between its P/C/B/U code and hex bytes, and decode the DTC status byte.
Open tool →MC/DCType a decision from your code or requirement. You get a minimal set of test cases that shows every condition independently changes the outcome, plus the independence pair for each condition.
Open tool →REQPaste your requirements, one per line. Each one is checked against common writing rules (INCOSE, ISO/IEC/IEEE 29148 and EARS) and you get the problems highlighted, with a score per requirement.
Open tool →SPICEAnswer 29 short questions on the main Automotive SPICE process areas to see where your team stands, where the gaps are and what to fix first.
Open tool →HILList the ECU's inputs, outputs and buses, and get the HIL I/O channel count and a ready Excel signal list for planning your test bench.
Open tool →One quick sign-in, no password or card, unlocks every tool.
Your DBC files, payloads and answers stay in your browser.
