@@ -136,14 +136,13 @@ names to all cells that participate in the witness framework:
These public names allow downstream tools to refer to individual properties by
their hierarchical path rather than by anonymous internal identifiers.
The `write_aiger -ywmap` option generates a JSON map file that includes, among
other things, ``"asserts"`` and ``"assumes"`` arrays. Each entry contains the
hierarchical witness path of the corresponding `$assert` or `$assume` cell.
This lets tools such as SBY map AIGER bad-state properties and invariant
constraints back to individual formal properties, enabling features like
per-property pass/fail reporting (e.g. `abc pdr` with ``--keep-going`` mode).
The `write_aiger -ywmap` option generates a map file for conversion to and from
Yosys witness traces, and also allows for mapping AIGER bad-state properties and
invariant constraints back to individual formal properties by name. This enables
features like per-property pass/fail reporting (e.g. `abc pdr` with
``--keep-going`` mode).
The `write_smt2` backend similarly uses the public witness names when emitting
``yosys-smt2-assert`` and ``yosys-smt2-assume`` comments. Cells whose
``hdlname`` attribute contains the ``_witness_`` marker are treated as having
private names for comment purposes, keeping solver output clean.
