(b) it is trivially subclassable +for test spies and real implementations; (c) it avoids imposing an async execution +model on synchronous converters. If async support is needed later, a thin adapter +wrapping the listener in an asyncio queue can be added without changing converter code. + +### Q: Should `rich` be a required or optional dependency? +**Decision**: Optional. `RichConversionListener` lives in its own module +(`conversion_listener_rich.py`) and does a guarded `import rich` at class +instantiation time. If `rich` is not installed and the user passes `--progress rich`, +a clear `ImportError` with install instructions is raised. This keeps the core +library free of heavy UI dependencies. + +### Q: How are phases reported for formats with unknown item counts? +**Decision**: `on_phase_start(phase, total=None)` allows `total=None`. The +`RichConversionListener` renders an indeterminate spinner in that case. After the +phase completes, `on_phase_end()` closes it. Converters should always pass a total +when they can pre-count items (e.g., `len(list(db.scopes(COVERGROUP)))`) and pass +`None` only when a pre-count would require a full traversal. + +### Q: Should UCIS-XML round-trip through Mem or SQLite internally? +**Decision**: Mem. XML is a complete lossless representation, so Mem is a natural +intermediate. The `DbFormatIfXml.read()` reads XML into `MemUCIS`; callers who +want SQLite persistence can convert afterwards. + +### Q: How granular should ConversionContext warnings be? +**Decision**: One warning per distinct unsupported feature type, not per instance. +e.g., "lcov: 3 covergroup(s) skipped" rather than one warning per covergroup. +This keeps output clean for large databases. + +### Q: Should vltcov writer generate `.dat` files or something else? +**Decision**: `.dat` files using the Verilator coverage data format. The writer +reconstructs the flat key=value format from UCIS hierarchy + code coverage bins. + +### Q: What is the LCOV reader mapping from LCOV → UCIS? +**Decision**: +- `SF:` file → UCIS file handle + DU_MODULE instance hierarchy +- `DA:` line,count → statement bin under BLOCK scope with source info +- `BRDA:` line,block,branch,count → branch bin under BRANCH scope +- `FN:` / `FNDA:` function → sub-scope under the module instance +- `TN:` test name → history node with TestData + +### Q: How are the UCIS-to-UCIS verify functions implemented? +**Decision**: Each builder function has a corresponding `verify_(db)` function +that asserts the exact expected structure. Both live in `builders/ucis_builders.py`. +This keeps builder and verifier in sync and makes test failures easy to diagnose. diff --git a/README.md b/README.md index 523945b..afe1ac0 100644 --- a/README.md +++ b/README.md @@ -182,6 +182,34 @@ pyucis convert --input-format vltcov coverage.dat --out coverage.xml See documentation for complete import examples and supported formats. +## Supported Formats + +PyUCIS supports bi-directional conversion between formats using the UCIS data model as the common representation.

This flat model works in all three backends (mem, xml, sqlite) and +all tests pass. The UCIS LRM also allows structured BRANCH/COND/EXPR *scopes* +but the flat model is the common tool output pattern. Do not break the flat +model while adding structured scope support. + +**SQLite specialized subclasses on read, not on write:** +SQLite's `createScope()` always returns a plain `SqliteScope`. Specialised +subclasses (`SqliteToggleScope`, `SqliteFSMScope`, `SqliteCovergroup`, etc.) are +only returned by `SqliteScope.create_specialized_scope()` when reading back. +This means `createToggle()` and `createScope(FSM)` currently return plain +`SqliteScope` objects, so FSM/toggle-specific methods are unavailable +immediately after creation. This is a significant usability bug. + +**Mem backend `createScope()` is strictly gated:** +Only DU_*, COVERGROUP, COVERINSTANCE, and COVERPOINT types work. All others +raise `NotImplementedError`. The fix is to add a generic `MemScope` fallthrough +for the remaining HDL/code-coverage scope types. + +**`RealProperty` enum is a placeholder:** +Only `b = 0` is defined. The four UCIS real-valued properties +(`SIMTIME`, `CPUTIME`, `COST`, `CVG_INST_AVERAGE`) need enum values and +implementation in both backends. + +**Attributes and tags exist in SQLite but not in the abstract API:** +`sqlite_attributes.py` implements attribute storage. It needs to be surfaced +through the abstract `Obj` class so all backends can use it. + +--- + +## Work Items + +Tasks are grouped into phases by priority. Each task has a clear deliverable, +the files to change, and what to test. + +--- + +## Phase 1 — Property Enum Fixes (no functional changes, unblocks tests) + +These are pure additions to enum files.

Key Design Decisions + +### Q: Which BLOCK_COVERAGE representation to use? + +**Decision**: Flat `statement` mode. The spec allows three equivalent alternatives +(process → block → statement, block → statement, or flat statement list). The flat +mode is the simplest to implement and sufficient for storing hit counts per source +location. No information is lost relative to what the Python DM exposes. + +### Q: Should CONDITION_COVERAGE ever be emitted? + +**Decision**: No. The Python DM does not expose the per-expression bin structure +needed for faithful XML. Writing partial condition XML would either be schema-invalid +or misleading. The writer emits `ctx.warn()` and skips condition scopes entirely. + +### Q: What should the writer do with unknown scope types? + +**Decision**: Skip them silently (debug log only). Unknown scope types are tool +extensions not covered by the UCIS spec. The writer should not fail. + +### Q: Should the reader fail on unrecognized XML elements? + +**Decision**: No — silently ignore unknown elements. This ensures compatibility +with UCIS tool extensions and future spec versions. + +### Q: How do TOGGLE_BIT names map between DM and XML? + +**Decision**: The `toggleObject.name` attribute = the TOGGLE scope name. Each +`toggleBit.name` = the bit's string name (e.g. `ff1[2]`). The 0→1 and 1→0 +transitions are identified by `CoverTypeT.TOGGLE01` and `CoverTypeT.TOGGLE10` +cover item types. Confirm with the existing `xml_reader.py` toggle reader code. + +--- + +## 8.
