Public FSDB waveform tools all call the vendor reader, NPI or fsdbreport

Survey of public GitHub repos that read FSDB waveforms, Nov 2026. kleverhq/wavepeek: its prebuilt binary does VCD/FST only; FSDB needs a Linux source build against local Verdi reader libraries. cxzzzz/wavekit needs Verdi NPI. nayiri-k/fsdb-parse is built on FsdbReader. SjInGithub/fsdb-waveform-probe shells out to fsdbreport. Tencent/wave-mcp auto-converts FSDB to FST. None of them decodes FSDB with its own code. So if your tool must run on machines without Verdi, plan for convert-on-a-Verdi-host (fsdb2vcd or fsdbreport), then open VCD/FST. Web search was off, so this comes from gh search repos fsdb plus a look at the READMEs; private or less visible projects may exist.
