rtl-model-consistency

A three-way consistency check compares outputs from your reference C model, BFM, and RTL on a shared test vector set, detecting implementation drift and regression risk across all three models.

The best way to compare RTL and reference model outputs is an automated three-way comparison script that executes the models in parallel and generates a per-vector consistency report.

You generate an automated RTL consistency report by running a scripted three-way comparison workflow, which outputs a markdown report scaffold detailing per-vector bit-exact results.

Yes, you can use a three-way consistency check as a pre-regression gate to ensure identical behavior across reference C, BFM, and RTL models before committing RTL changes.

You need a SystemC TLM BFM if you want to perform a three-way consistency check, as the workflow specifically compares the BFM against the reference C model and the RTL implementation.

You should use a three-way consistency check instead of standard RTL simulation when you have reference C and BFM models and need to verify bit-exact similarity across all implementations early.
