## [Unreleased]
|
||
|
|
|
||
|
|
### Added
|
||
|
|
|
||
|
|
- `boxsim` command line tool with `decode`, `extract`, `netlist` and `build` subcommands.
|
||
|
|
- Pure Python implementation of the A2F codec, so decoding no longer needs `Boxsim.exe` or a CPU emulator. Verified byte-identical to Boxsim's own decoder across all 134 containers in the distribution.
|
||
|
|
- Project model covering `#General`, `#Weiche<n>`, `#Chassis<n>`, `#Einbau<n>` and `#Schallwand<n>`, with the crossover grid decoded to an electrical netlist.
|
||
|
|
- Symbol resolver driven by Visaton's `Visatonteile.txt` catalogue, matching values numerically against the KiCad library. Infers an omitted series from a sibling part, reports DC resistance deviations, and refuses to substitute an unstocked value.
|
||
|
|
- KiCad 10 schematic generation that preserves the Boxsim grid layout, including wires, junctions, flattened derived symbols and deterministic UUIDs.
|
||
|
|
- Verification gate comparing the netlist KiCad extracts from the generated sheet against the netlist derived from the Boxsim grid, plus ERC.
|
||
|
|
- Docker image bundling the tool, the Visaton library and the parts catalogue, with a build-time check that the bundled catalogue is complete.
|
||
|
|
- Development-only oracle that runs Boxsim's own `ExpandA2F` under Unicorn, and `tools/difftest.py` to differentially test the codec against it.
|
||
|
|
|
||
|
|
### Changed
|
||
|
|
|
||
|
|
- Emulator hooks are bound to their trap addresses instead of every instruction, cutting a decode from 69 s to 14.5 s with identical output. The pure Python codec then brought it to about 1.6 s.
