Read the results

Each configuration describes one model, one memory setup and one runtime choice. The bundle records the inputs and the evidence behind its outputs.

File Purpose
run_summary.md Human-readable result summary
run_summary.json Structured result contract
run_summary.csv One row per measured invocation (measurement.index, measurement.cycles.total); one shared row without samples
manifest.json Bundle files, roles, sizes and hashes
config.yaml Configuration generated by helx run-case; not created by config-driven helx run
input_config.yaml Original input configuration
artifacts/ Compiler and analysis outputs
Terminal window
uv run helx show results/kws_vela_only
uv run helx show results/kws_vela_only --json
uv run helx validate bundle results/kws_vela_only

Check the platform revision, stages, engine and provenance before using any metric. A missing simulation stage cannot establish simulated latency. An estimated value is not a hardware measurement.

JSON samples live under measurements.samples[i]. Use helx export --fields statistics for aggregate rows.

Use helx export --help to combine bundles into a table. Keep the provenance fields alongside the metrics when comparing runs. The result schema defines the fields.

The following is an abbreviated illustration, using the CLI’s section names. All metrics, platform names and revisions below are dummy values, not an Ambiq benchmark or calibration data. Omitted sections are marked with ....

The experimental FVP PMU estimate uses simulator counters and a platform energy model. It does not mean energy was measured on a physical board. The example’s dummy total is 20 µJ, split into 10 µJ core, 6 µJ SRAM and 4 µJ external-memory energy.

This illustrative reading of a result uses dummy values only:

Metric Dummy value Read it as
Latency 2 ms Example inference duration, not a hardware claim
Average power 10 mW Example modelled power over that duration
Energy 0.02 mJ Power multiplied by duration

The numbers are internally consistent to show how the fields relate; they do not describe any real model or silicon. Use your own bundle’s provenance and metric basis when reporting results.

Vela-only runs do not show executed FVP counters. Their predicted energy, when available, is shown separately as Experimental energy (Vela estimate). Do not compare a compilation-only prediction to an executed result without retaining that distinction.
