ADTC / EDA Workshop 2026: C-Trace — An Open-Source RISC-V® Trace Encoder and its Ecosystem

Albert Schulz presented “C-Trace — An Open-Source RISC-V® Trace Encoder and its Ecosystem” at this year’s ADTC / EDA Workshop 2026.

In the presentation, he introduced C-Trace, Accemic’s open-source, standards-compliant RISC-V® trace encoder developed within the European TRISTAN project. C-Trace addressed a key gap in the RISC-V® ecosystem: a production-grade, standards-based trace encoder enabling non-intrusive observation of real program execution, timing, coverage, and fault-analysis evidence for safety- and security-critical systems.

The talk also highlighted how C-Trace integrated with standard RISC-V® trace interfaces end to end, from the Trace Ingress Port and Trace Control Interface to Nexus 5001™-compliant output streams, and how it connected to the wider trace ecosystem, including decoders, FPGA demonstrators, CEDARtools®, and analysis tools.

C-Trace was presented as part of Accemic’s contribution to the TRISTAN project and is planned to be released as open source at the end of the project in mid-2026, together with a decoder and FPGA reference demonstrator.
