A non-intrusive, open source tracing solution for virtually any RISC-V CPU. Based on N-Trace specification. Implemented in SystemVerilog — open source and commercial license model available.
Most RISC-V trace IP is a black box. The CEDARtools.TraceEncoder isn’t. It’s an open, standards-based N-Trace encoder you can read, adapt, and prove in your own SoC — with standard AMBA interfaces, an open testbench, and a real integration example rather than a datasheet promise. Built in the EU TRISTAN project and paired with an open decoder and trace format, it’s transparent end to end. Start open-source; license commercially when you need to.

Software Nexus decoder with support for CEDARtools.TraceEncoder specific messages – Fork from riscv-nexus-trace/refcode
Universal trace format for architecture-agnostic trace analysis. Text and binary encoded. Including all common low level trace event types.
